The Scotch 6015 Glue Stick offers a pH-neutral and acid-free adhesive, making it a suitable choice for archival work and photo preservation. The .52 oz volume is a mid-sized option that provides enough product for multiple projects while remaining easy to handle. When the glue is fresh, it spreads smoothly and provides a reliable bond for paper-to-paper applications.
The casing is made of flexible polypropylene, which protects the adhesive core. However, the product is sensitive to environmental conditions; in low-humidity areas, the core can become brittle over time. If the adhesive hardens, the twist mechanism may be prone to snapping when turned. To maximize the product's lifespan, ensure the friction-fit cap is pushed on firmly, as there is no secondary gasket to prevent evaporation.
Because it is a non-toxic and washable formula, it is a safe option for use around children. It should be noted that this glue has low shear strength and is not intended for non-porous surfaces such as plastic or metal. It is most effective on standard bond paper where it can achieve a mechanical "bite."
If you are looking for an adhesive with more visual contrast to help with placement, you might consider the Amazon Basics purple sticks as an alternative.
