Made of high quality, weather-resistant stainless steel, this ultra-handy accessory with its dual spring gates will hold, secure, and connect everything from keys to water bottles to gear. This smaller-sized S-Biner #1 is excellent for connecting two zipper sliders on backpacks, duffels, and suitcases. This size also works great for hanging smaller items from a purse or backpack strap, attaching to individual keys, or even hanging a plant from a ceiling hook.
