The anchor keychain-bottle opener is made out of stainless steel, which offers corrosion resistance and durability. It comes with a 1″ diameter nickel plated split key ring (not shown). The dimensions are 3.0″ tall by 1.4″ wide, not including the ring. The stock (the cross member at the top of the anchor) and the fluke (the end of the anchor hook) precisely act as the bottle opener.
