"The Nite Ize S-Biner Ahhh Dual Carabiner Clip Bottle Opener is made of high quality Stainless Steel. Like our classic S-Biner, both ends of the S-Biner Ahhh feature sturdy gate closures, making it a multifunctional carabiner that you can use to attach and carry keys, water bottles, and camping gear; hang lanterns and lights; or clip two items together. But we didn't name this little puppy the ""Ahhh"" for nothing - both ends function as bottle openers, too. That means that when you carry the S-Biner Ahhh wherever you go, you'll always be able to pop open a bottle of your favorite beverage, making you the envy of thirsty people everywhere. Designed to be portable yet functional, this S-Biner measures 3.18 x 1.76 x .28 (80.95mm x 44.73mm x 7.32mm) and weighs 1.16 oz (33g).
