These Bottle Openers measure 2.5" X 1.25" on the bottom by the actual opener. They are made from zinc alloy and are plated in a PEARL NICKEL finish. This is a little shinier than a matte finish, but no where near a shiny silver finish. Each piece is attached to a 1 1/8" flat split ring. Packaging is bulk, but also available with 12 pieces on a header card (SMBOKT20/12).
