These are super durable voile straps. The nano size is easy to use for everyday purposes. They come with buckles, which are not usually included, so you can neatly manage any excess strap. This is a set of 3 with buckles. - Only one backing card is included. - One strap has a slight bend from being bundled together, but it should straighten out quickly. Thank you. Here's a description: "VOILE STRAPS" were invented in the 1980s in Utah, USA, as binding straps for skis. They are made of tough nylon buckles and a very durable stretch polyurethane band that is resistant to UV degradation. The biggest feature is that they can be tightened with a strong tension and will never loosen. They are great for replacing lost straps, and by replacing the straps on your saddlebags or handlebar bags, you can secure them more firmly and quickly attach and detach them. The 6-inch (approx. 15cm) length is the most convenient for securing bike bags to handlebars and around the saddle. The 9-inch (approx. 23cm) length is also perfect for securing spare tubes and frame pumps to the frame. You can also connect two straps together when you need a longer length. The uses are up to your imagination. They can be used in a variety of ways, from the outdoors to the garage, as a replacement for Velcro and nylon straps. They are also useful for securing "WALD" baskets to racks like the M-1. SPEC Buckle: Nylon Strap: Polyurethane Length: 6 inches (approx. 15cm)
