Smaller-sized S-Biners?é?« are excellent for connecting two zipper sliders on backpacks duffels and suitcases. We know that one size doesn't fit all so we've designed six different sizes so you can choose the right size for the task at hand. We've found that the smaller sizes work great for hanging smaller items from a purse or backpack strap attaching to individual keys or hanging a plant from a ceiling hook. The larger sizes work great for bigger jobs like hanging a paint can from a ladder or a tool to your tool belt. But the list goes on and on.
