No Other Choice For A Custom Plastic Chastity Device

This is the nylon device I tested. It’s 3D-printed. While the material looks solid, it’s actually quite porous. (Click image to enlarge)

As you might remember, I reviewed the Custom Chastity Ghost chastity device a while ago. This device has proven to be one of the most difficult to review I have ever tried. It manages to be a combination of the best fitting device I have ever worn and the most difficult to actually wear.

This device is 3D printed. The makers don’t admit it, but it is obviously from a public 3D printing company. That’s actually good news. Many use a medical grade nylon material. It has  low melting point, but nothing that affects wearing the device. It does, however, figure in to the big problem.

Let me get right to the point. 3D printers do not output glass-smooth finishes, far from it. The surface is almost like sandpaper. It’s very abrasive, particularly to sensitive genital skin. What frustrates me is that I have contacted Custom Chastity about this issue and they either claim it doesn’t bother others or just silence. Interestingly, they pack silicone lube with every unit. They know the low quality finish is difficult to wear without some protection.

Ordinarily, I would leave it at that. I would consider the custom cage to be an expensive failure. Expect to pay about $250 for a custom Ghost like mine. But I can’t let it go. The reason is that once the sandpaper finish is removed, it is the most comfortable device I have ever worn. The nylon material is very light and strong. I am generally unaware it is on me.  The padlock (included) fits into a slot (you can see it at the right side of the photo) that keeps it in place so it is always lying flat on the top of the device; no more rattling.

The design, even after being reworked to my very-short 1-1/4-inch length, is perfect. It fits me like an invisible glove. The owners of Custom Chastity are a married couple. She, apparently does all the 3D design work. He does the website and presumably wears one of their devices. Their website is improving, but is truly difficult to understand. Their fitting instructions are obscure, at least to me. I got my measurement wrong the first time because the diagram they provided confused me.

The wife communicated with me. Most of the time she didn’t seem to understand what I was saying/asking. It was a frustrating process. When I wrote them about my review and my problem with the finish, they just brushed me off saying they have the device tumble-finished. Guess what? It doesn’t work. In contrast, Mature Metal is very responsive and will do anything they can to make their devices work for each customer. The Ghost is a plastic version of the Mature Metal Jail Bird. It is smartly designed.

Because this device has such good potential, and because I invested so much in it, I decided to try to fix the finish. I had two cages: the first one that was too long, and the one that actually is a perfect fit. So I experimented on the one I couldn’t wear. I tried using a Dremel machine with sanding drums. It melted the plastic.  Tom Allen suggested that I just hand sand. So I bought a package of sand paper from Amazon.

I started with 150 grit. It took about two hours to smooth the areas that touch my skin. I then worked through progressively smaller grits until I finished with 400 grit. I then cleaned the device in hot water (100 degrees F.) using my ultrasonic cleaner. I got a smooth finish that I can wear. It took me about three hours for the ring and cage. It wasn’t hard work, but it was tedious.

I’m wearing the device now. Mrs. Lion put it on me on Thursday night. I asked if I can wear it for at least a week. I want to be sure that when I go on my next business trip, I can be locked into it with a plastic seal and be able to stay in it for the entire trip. It’s a bit irritating, but so far wearable.

I am impressed with the use of 3D printing to create a truly custom device. The other device by Pedro isn’t wearable at all. The design makes peeing without a ball bath impossible for me. The ring is super wide and therefore difficult to wear. The Ghost’s base ring is thicker than the stainless steel Jail Bird’s. That’s needed since nylon is weaker than steel. It’s possible that there may be too much friction with this device. If there is, I will try the silicone lube as a way to help.

I’m wearing the Ghost. Note that the generous front opening allows my urethra to peek out. If it moves, it is easy to recenter it. My balls are out of the way so peeing is easy. (click image to see larger)

I’m trying so hard to make this work because as far as I know, there is no other custom plastic device out there. I need a very short cage. The “small” versions of the other products on the market are generally longer than 2-inches. I want a device that fits like a glove. If my urethra peeks out, my ability to pee is improved a lot. The device works with numbered, plastic seals. That means there is no metal, so airport metal detectors won’t be tripped by the device. You can also use a small plastic tie to fix it tightly and still fit in the numbered seal. This is great security for travel.

Numbered seal on Ghost. The red-colored area on the ring is there because the original color of the ring was red. You can see how intense the sanding needed to be extensive. It took off the paint.

I can’t pack a nail clipper due to security requirements. So, removing a plastic seal requires shopping for a clipper and then removing the seal. Since the seals are numbered, I can’t hide the fact I took it off from Mrs. Lion. You can see the tag (left). It nicely fills the hole. The red color is from the ring. We misplaced my white ring. It’s probably around because I was sanding it. You can see there is very little red color left. The sanding took it off.

Here we have a very well-designed device with a flaw that under most circumstances would disqualify it from consideration. But, and this is a very big but, there is nothing else out there that in my case, will work.

I think that most people who wear chastity devices full time will agree that the best way to live with a device is by having one that fits perfectly. Long-term wear with an off-the-shelf product frequently becomes unbearably uncomfortable. Once a custom made device has been adjusted (most of us send our devices back for adjustment), it can stay on as long as desired. I’ve been wearing a Mature Metal Jail Bird for over 3 1/2 years.

I’ve worn the Ghost for about ten days. After a few hours of sanding, without lube it is completely comfortable. That’s the good news. The bad news is that the nylon its made of is porous. That shouldn’t surprise me. 3D-printed objects are always porous. That’s not a problem in terms of strength, but it does cause me a bit of concern. Those pores in the nylon pick up organic material and start to smell. After ten days, the back of the base ring had an unpleasant odor. I shower every day and make sure I wash the cage as best I can. I move the base ring away from my body and soap it up and rinse thoroughly. That isn’t enough for this device.

To be fair, the smell isn’t detectable unless you actually sniff the ring. When I was removing the ring for play (I remove and put on the ring, Mrs. Lion handles the actual cage.), I noticed a faint scent. Further investigation revealed the back of the base ring (the part that touches my body all the time) had an unpleasant smell. I put the device through our ultrasonic cleaner with the special detergent. That removed all traces of the odor.

I expect that soaking the device in a cleaning solution would also work. My concern is that with long term wear, which is what I do, the smell would build up and become detectable to others. Also, there is a real chance that organic material in the porous nylon could incubate bacteria in the warm, damp environment and eventually cause skin problems for that area.

This isn’t a problem with the stainless steel Jail Bird. Steel is not porous at all. Any crud it accumulates is easily washed off. The fact that the smell (not urine scent by the way) remained after daily showers is concerning to me. It means that I can’t prevent the problem while I wear the device. That’s too bad. It’s super comfortable and very light weight.

Because of this potentially dangerous defect, I don’t recommend long term wearing without regular cleaning with an ultrasonic device or some very strong solution that can get into the pores of the device. Weekly cleaning should keep things safe and sweet smelling. I will still be wearing this device for trips that include air travel. Twenty-four hour wear for a week or two is probably safe. When I wear it in the future, I will pay closer attention to the back of the ring and try to scrub it with soap and a washcloth while I am wearing the device. Anti-bacterial soap is a good choice for this.

There is another plastic device, at least mostly plastic, made by Steelwerks. I’m unlikely to try this device. For one thing it is a full tube, and I prefer a cage. For another, it costs well over $1,000 USD. That’s much more than I can afford. For now, at least, if you want a plastic device that fits, Custom Chastity’s products are the only ones on the market. To make their products wearable, you will have to sand them for hours. Maybe someone will see the need for a well-finished plastic device and give us a choice.

The Custom Chastity devices are very well designed. That have two potentially-fatal flaws: As delivered, they have a rough finish that irritated me in just a few hours and actually removed sensitive skin on my penis. Two or three hours with sandpaper will fix that. The other problem is that the nylon is porous and will collect material from your body. Normal showering, with attention to the device, didn’t prevent a bad smell after ten days. Combined with the irritation from the rough finish, if you don’t smooth it yourself, is a great opportunity for infections. This can be prevented by regular cleaning with an ultrasonic cleaner with detergent.

My advice about this product is that if you are willing to smooth the rough 3D-printed finish and sanitize the porous nylon that the device is made from, I think you will be happy with this as a long term or travel device. With a plastic, numbered seal, the device is comfortable, secure, and undetectable when you go through metal detectors. I will be wearing mine on my next trip.

In summary this is a Buy with caution recommendation.

    I’m just starting out in chastity and have 2 of Pedro’s devices. The first is from the X3 range and is a fully enclosed tube but is a bit tight. Choosing the correct ring in this range is essential. The second of from the Q4 range and is more of a traditional cage. The rings are much easier to select. I agree about the finish though as they are sold as polished but this only means a tumbled finish. I will set about it with the sandpaper and hopefully this should make it all the device I need at the moment.
    The other thing I liked about Pedro’s cages are that they lock with a magic locker type device like the holy trainer so no padlocks or plastic tags to snag or bump about.

      Also Pedro makes a custom fit tube/cage for the Q4 range.

        I have this problem with custom chastity also, irritates all the skin around my balls in just a few hours, I’ll try sanding it, I was wondering if there is s safe acrylic sealant or clear coat that could work

      He made me one in my size: 1 1/4″ tube. The tip was nestled on my scrotum. Peeing was messy.

    Maybe you don’t think of this as an option b/c it requires a piercing but EvotionWearables are 3-D printed, custom devices. However, they are finished rather than being raw nylon. Also, they use laser sintering instead of deposit printing so it’s a much finer surface than this device. I’m torn between EvotionWearables & Rigid Chastity. I think the design of EV is much better thought out. But I really want steel. I’m still healing from my piercing & need to stretch the hold from 8G to 6G. Then I’m ordering. I’m hoping something will happen between now & then to help me make up my mind…

    What about the nylon chastity device by evotions?
