Leather glue is a type of adhesive specifically designed for bonding leather materials together. It is often used in leather work and in the repair of leather products such as clothing, shoes, and furniture. There are many different types of leather glue available on the market, which can vary in terms of strength, durability, and flexibility. Some leather glues are formulated to be particularly flexible so that they don't crack or break when the leather moves. Other leather glues are formulated to be particularly strong in order to hold tight joints or withstand high loads. It is important to choose the right type of leather glue for the task at hand and to carefully follow the manufacturer's instructions to ensure that the glue dries properly and holds the leather together in the desired manner.
