Glue sticks are adhesive tools commonly used in arts and crafts. They come in a cylindrical shape and contain a solid adhesive that can be applied by twisting the bottom to expose the glue. Glue sticks are popular for their ease of use and mess-free application, making them ideal for children and adults alike. These adhesive sticks are often used for bonding paper, cardboard, and lightweight materials. They dry clear and are typically non-toxic, which makes them safe for school projects. Glue sticks are a convenient alternative to liquid glues, as they reduce the risk of spills and drips.
