A glue stick is a type of adhesive that comes in a cylindrical form, typically made from rubber or plastic. It contains a sticky substance inside which can be easily applied to surfaces using its built-in applicator. The term “glue stick” refers both to the actual product and also to the act of applying it with the attached brush or roller. Glue sticks are commonly used in offices, schools, and homes for a variety of tasks such as mounting photos, attaching papers together, fixing small objects, and more. They offer an easy-to-use and convenient method for adhering different materials without the need for messy liquid glues or heat-activated adhesives.
