This is a key chain that can be used as a bottle opener and a two finger ring. It is machined out of premium Aluminum, Brass, Copper, and Stainless Steel using a high precision CNC mill in our warehouse in Las Vegas, NV.

The small ring size for fingers is 0.68″ in diameter (17.3mm or ring size 7)
The medium ring size for fingers is 0.79″ in diameter (20.2mm or ring size 10.5)
The large ring size for fingers is 0.9″ in diameter (23mm or ring size 13) (This size is pictured for the first photo)

Larger hole sizes can’t be made on this model and we currently don’t have smaller hole sizes available.

The dimensions are 2.2″ x 1.35″ x 0.375″. The hole to fit on a key chain is 0.158″

The natural finish will have machine marks. The stonewashed finish is from tumbling and reduces the appearance of machine marks. The first 3 photos are of the natural and the last 3 are stonewashed
