HomeBrew bottle tag

This tag serves 2 purposes:
1 - to help me identify which beer is which in the beer fridge (I homebrew)
2 - A way ti use up those small amounts of plastic left on the spool

They go onto the bottle and come off quite easily, but have not yet fallen off accidentally. When a specific brew is fully consumed the number I wrote on with a sharpie marker comes off with a little rubbing alcohol and can be reused again and again
