Made of high quality and weather resistant stainless steel, this carbine with a thousand uses will hold, secure and connect everything from keys to water bottles to equipment. The smaller sizes of S-Biner help you connect zippers on your backpack, weekend bag or suitcase. We know that one size does not fit all, so S-Biner is available in six different sizes so you can choose the size that suits you and your purpose best. We have tested the S-Biner and come to the conclusion that the smaller sizes are suitable for hanging smaller objects on the handbag or backpack, attaching things to the keychain, or hanging plants on a hook in the ceiling. The larger sizes can do larger jobs such as hanging the paint can on the steps or a tool in your belt. The list of purposes can be made long so we choose to quote Backpacker Magazine "Do not ask yourself if you need this useful little widget. The question is: how many?"
