Our Ring Opener comes in as the lightest and most inconspicuous of our hand attached bottle openers. Simply slide this anodize aluminum, masterpiece over your strongest finger and you're ready for action. Current available sizes: Medium (Red, Ring size 10), Large (Blue, Ring size 12), and X-Large (Black, Ring size 14). Hint: If these current sizes are too big, you can build up some padding (which also cushions the pressure) to make them fit. Some crafty bartenders have cut a waterproof Velcro™ self adhesive strip (fabric side) to fit the top inner side of these rings and have claimed great results. You can use a ruler on a ring that fits, to determine your size.
