Glue sticks are adhesive tools commonly used in arts and crafts. They come in a cylindrical shape and contain a solid glue that can be applied by twisting the bottom to expose more glue. When applied to paper or other materials, the glue sticks create a strong bond that dries clear and is often washable. These sticks are popular in schools and homes because they are easy to use and mess-free. Unlike liquid glues, glue sticks do not spill and are less likely to create a mess. They are ideal for projects involving paper, cardboard, and photos.
