You must have used these in childhood (in case you aren’t using them still for some purpose or the other). Glue sticks contain a cylindrical roll of soft and mushy adhesive inside a plastic tube that can be directly applied to the required surface by rubbing it a couple of times. It dried rapidly once applied and is very user-friendly in terms of both handling and cleaning. Good quality glue sticks offer durable adhesion but in some circumstances, you might notice the earlier joined papers starting to get loose.
