While cool, I dunno that I’d recommend wearing this very often. Particularly around law enforcement, since the bottle opener ring could definitely be mistaken for brass knuckles.
The bartender ring is made from stainless steel, and is worn like a, well, a ring. It’s handcrafted and sold by Dustin Wallace, and each one is made to order apparently. We don’t know how much they cost, but you can order one from the Maker’s Market. Perhaps you might be better with the Ring Thing, which will set you back $7.99 and isn’t considered to be a deadly weapon in California and New Jersey.
