The 7g Elmer's Disappearing Purple Glue Stick is a standard tool for secondary education and home crafting. It uses a pH-sensitive dye that appears purple upon application and turns clear once dry, allowing users to track their progress and avoid missing spots. The formula is specifically designed to prevent paper from wrinkling, a common issue with liquid glues, by using a higher solids content in the synthetic polymer matrix.
The housing is made of high-density polypropylene, which allows the twist mechanism to operate smoothly without jamming. Because this product is acid-free and photo-safe, it can be used for long-term projects like scrapbooking without damaging the paper or causing yellowing. To protect the glue from drying out, the cap must be fully engaged; if left uncapped for more than 15 minutes, the surface will begin to harden and lose its effectiveness.
While these sticks are durable, the 30-count tray can be flimsy for long-term storage. It is often more practical to move the sticks into a more permanent storage container to prevent the twist bases from being damaged by impact. The glue is 100% water-soluble, ensuring that it can be cleaned off skin or out of clothing using a standard warm laundry cycle.
For even smaller projects or younger children who might struggle with a 7g stick, the 6g version provides a slightly more compact alternative.
