I got these for my cheeks, and am thrilled. They're perfect. Once I figured out how to put the first o-ring on, the second was a breeze. These may be the most comfortable things I've put in my cheeks yet.

got as a retainer for tongue, considering how much I bite my tongue ring accidentally, would not wear unless I had to

Anytime I have to hide my tongue piercing, I wear this piece. It is comfortable and virtually invisible.

I have had retainers in the past and they have been plastic. I was going to start a new job and needed to buy retainers. I decided to try the glass retainer and to my surprise, it did not have the etching where the o-ring sits. I tried it on my day off and the tongue ring didn't fall out, so I was pleased. I typically wear retainers for the 5 days I am at work and then take them out but this tongue ring irritated the bottom of my tongue, so I didn't wore it two days in a row and took it out. I wore my other retainers and a few days ago decided to wear the glass retainer again. I planned on wearing it for the day and take it out that night but ended up eating it on accident. I didn't realize the hard crunch was my tongue ring. Usually it doesn't feel like I have anything in, so it wasn't until I went to take it out that night, I noticed it was gone. The crazy thing is I remember while I was snacking on popcorn, feeling this a crunch like shattered glass. I thought it was the kernel and ended up spitting it out in a napkin. I am shocked at how easy the glass was to chew. Luckily I didn't swallow the glass or at least not all of it. However, I think it is dangerous that the glass is that malleable. Since the tongue ring doesn't have a place for the o-ring to lock in place, it can easily come out. I think it is best to get the other retainers if you work a full-time job, where you eat lunch or snack on breaks. I find the flexible no-see-um barbells to be better. I also like the clear tongue retainer that looks like a barbell but all plastic.

These are a life saver as I was able to wear them during general anesthetic for surgery. They seem sturdy and high quality, and they make your piercing barely visible when needed!

Fits perfectly, is comfortable and looks pretty good for a bridge piercing retainer, doesn't stand out too much.

Good quality, and very shiny and comfortable!

I love this, it's a life saver. It fits a little snugly but I prefer that to it being too long. Perfect if you have to cover up piercings and what not because of work and/or family. It looks a little strange if you stick your tongue out or open you mouth too much, since its see through but there's no flashing metal or anything when you talk so it's perfect for what I need it for.

I bought 2 to keep my nipple piercings open during surgery. They worked like a charm! Decent quality for the price.

Great for hiding a tongue piercing! Just be careful as this thing is super clear and easily lost, the tiny o-ring is a bit tricky.
