DFTOA 5 PACK Stainless Steel Flat Bottle Opener with Keychain- Bar Key-Beer Bottle Opener for Kitchen, Bar or Restaurant（Black）

These rust very easily I put them for my outside bar. They got water on them and it rusted waste of money

Very rough and sometimes breaks tops of bottles shards of glass in drink so be very careful

Party favors guest loved them. Planning to order more for next party!

I hoped that these might be multi-functional and useful for popping open mason jar lids, but they were not. For what they were explicitly designed for, they are probably great, but they are limited in usefulness.

Can attach almost anywhere. I hung one in garage rack and on our Ranger.
