A fastening strip is a type of material used to secure objects together. It can be made from a variety of materials, such as leather, fabric, or plastic. Two common types of fastening strips are straps and thongs. Straps are usually made of leather or fabric and are used to hold items together, such as luggage or backpacks. Thongs are usually made of plastic and are used to secure items such as clothing or shoes. Both straps and thongs are used to keep items in place and provide a secure fit.
