Art's correct, it really doesn't leave any residue. I wrapped some around the handles of my Snowpeak Ti cup and boiled some water on the stove to test heat resistance. Flame was about 2" from the silicone. No melting/burning and it insulated the handle well enough to touch with bare hands. I've also wrapped the P38 can opener I keep on the keychain. I usually wrap it with regular tape to keep the edges from poking holes in my pants pocket but it leaves a sticky residue. I'm interested to see how well it holds up on keychain duty.
