Glue sticks are solid, twist-up adhesive sticks—similar in appearance to lip balm—designed for clean, direct application onto paper, cardstock, fabric, and other porous surfaces. The formula typically contains non-toxic polymers like PVA or PVP, emulsifiers, water, and softeners, creating a smooth, even bond as the water evaporates upon contact Invented in 1969 by Henkel under the Pritt brand—so iconic that “Pritt Stick” became a generic term—the glue stick revolutionized arts, crafts, office tasks, and schoolwork. Compared to traditional liquid glues, glue sticks offer a safer, mess-free experience: they’re portable, fast-drying, washable, acid-free, and often solvent-free and kid-friendly Ideal for pasting paper projects, scrapbooks, posters, and classroom assignments, they leave neat, residue-free bonds without soaking or warping materials—making them a staple in every craft box and study kit.
