Glue sticks are adhesive tools commonly used in arts and crafts. They contain a solid form of glue that can be applied by twisting the base to expose the glue. When pressed against paper or other materials, the glue sticks adhere quickly and cleanly, making them ideal for school projects and scrapbooking. These sticks are often favored for their ease of use and mess-free application. They come in various sizes and can be used on different surfaces, including paper, cardboard, and photos. Glue sticks are non-toxic, making them safe for children to use in creative activities.
