Using these on the mounting screws of my keyboard case. I also have smaller ones i use on the stems of some mechanical switches to reduce post travel. I think they work way better than keycap o rings so long as you have short springs. Also remember itll up the springs force a bit due to making them function in a smaller space than normal sorta like using longer springs but not ;)

I bought these to fit the back of my 12g tunnels in my stretched ears. They fit great and will most likely be able to be worn as I stretch up a few sizes. I love that so many are in the pack because they are tiny and easily lost. They also come in various sizes to repurchase as I stretch up. This was precisely what I was looking for, and it filled the need!

Ladies and gentlemen, gather 'round, for I am about to regale you with a tale of epic proportions involving none other than the unsung heroes of plumbing and compression – the uxcell Silicone O-Rings! They may be small, but trust me, these little donut-shaped dynamos are the superheroes your pipes have been waiting for!Now, I know what you're thinking – O-Rings? Sounds about as exciting as watching paint dry on a rainy day, right? Wrong! These tiny white wonders are the Gandalfs of the plumbing world, shouting, "You shall not leak!" with every snug fit.First, let's talk about the size – 4mm OD, 1mm ID, and 1.5mm width. These numbers may seem insignificant, but let me tell you, they pack a punch. It's like having the precision of a master sushi chef in your toolbox.The VMQ (Vulcanized Silicone Rubber) material is so durable that I'm convinced these O-Rings are secretly made from the same stuff as superhero capes. They've faced scorching temperatures, icy chills, and the relentless pressure of my clumsiness, and they've emerged unscathed every time.But it's not just their strength that's impressive; it's their versatility. I've used them in compressor valves, pipes, and even to fix my showerhead. These O-Rings are like the MacGyver of the plumbing world – they can solve any leaky situation with a wink and a twist.As for the color, they may be white, but they're the unsung heroes that turn potential plumbing disasters into peaceful pipe symphonies. They're the plumbers' equivalent of angels in disguise, silently working their magic behind the scenes.In conclusion, the uxcell Silicone O-Rings are not just gaskets; they're guardians of your plumbing kingdom. They've saved my bacon (and pipes) more times than I can count, and I'm convinced they have secret meetings with the wrenches and pliers to keep my household running smoothly. So, do yourself a favor and invite these little heroes into your toolbox – they'll be your trusty sidekicks for generations to come!

I have a glass plug in my ear that makes keeping the back on especially tricky. I got the 2mm after reading reviews of failed attempts at using some of the smaller sizes. They appear tiny but have just the right amount of stretch to get around my jewelry. They were hard to get on only because of the size, but once it got it on it was nice and snug.

Make sure you know both the inside and outside dimensions as they cannot be stretched too far without breaking.

Used for a DIY on keyboards to 'burger' mount the standoffs! Makes a small but noticable difference!

Worked excellent for my o ring mount on my tofu65. I got a great deal of flex as well as a more "even" sounding keyboard.
