The Bike Beer Bottle Bro!

Zip-tied bottle opener. Perfect on your bike or on any of the bike poles you want or desire! Needs one magnet (size 10X3mm) to catch the cap. You can attach it on cylinder of diameter around 26-32mm.

Setup magnet by pressing or hammering them into the part. It's better to secure permanently in place with superglue. There is also a version without the magnet!
