KidderCorp bottle openers have become a welcome addition to the Challenge coin market. KidderCorp’s Military Bottle Openers provide a functional alternative to traditional coins that can be used to open drinks while also being displayed with pride. Bottle openers are made with the same high quality metal and paints used in our award winning Challenge Coins. Custom shapes and sizes are possible while still maintaining functionality. KidderCorp Bottle Openers make excellent gifts and mementos to pass out at your retirement.
