They’re clear and small enough to not be too noticeable. Great adhesion. Works fine nothing extraordinary. I need such small pads for small items like urc mx-3000 remote.
Also, very rubbery so does not maintain the shape. Do not buy these, useless. Instead they help it slide because they are so slick.
It's hard to determine the size in millimeters. They are microscopic. Arrived in a generic plastic bag with no branding and a made in china sticker.
No more worrying about the hard wood floors being scratched and gouged by chairs. Reduce fiction and noise withe the ground effictively and very durable. They * my dining chairs and other items they fit on.
