This 5-pack of Elmer's School Glue Sticks features the "Disappearing Purple" formula, which provides a high-contrast visual guide for children and hobbyists. The purple tint allows you to see exactly where the adhesive is being applied, then turns clear as it reacts with the air and dries. The formula is acid-free, helping to prevent the long-term yellowing of paper in scrapbooks or school projects.
The twist-bottom mechanical feed is housed in a polypropylene casing. To keep the glue from hardening, it is essential to press the cap on with significant force; if the cap is not fully seated, air can leak in and cause the glue to "skin" over or dry out within a few days. If the glue becomes too dry, the internal screw-drive can seize and may snap if you try to force it to turn. The bond is specifically designed for porous materials and will not hold securely on plastic or metal.
Safety is a priority with this design, as the washable formula meets ASTM D-4236 standards. This makes it a helpful tool for early childhood development, where mess and safety are constant considerations. However, the mechanical feed is not serviceable, so once the internal screw is stripped or the glue has dried significantly, the unit will no longer function properly.
If you find that these smaller sticks run out too quickly, you might find the 30-count bulk pack more convenient for a busy school year.
