I know this is practically a sin in the Bitcoin world, but I'm not at all entrepreneurial. Having gotten a Bitkey I now plan to get them for all of my family members, but the problem is they all look alike. Someone please make some Bitkey Bumpers. A simple silicon or similar bands to stretch around it that comes in various colors would suffice. Until then, I might just try a rubber band or maybe printing something from TPU (or is there a better material.)
