These real rubber bands are way better than some of those flimsy sythetic substitutes out there. No unnecessary colors added just plain old-fashioned functionality...some things just don't need to be changed and these haven't been.
On remote control devices the hinges for the little battery door or the latch itself often becomes useless. I triple wrap the remote with the bands to hold the batteries in place and as a benefit the remote is not so slippery on the table anymore.
