Glue Stick Astra 21 g — single stick for paper and craft bonding

Astra glue stick 21 g is a twist-up solid adhesive designed for bonding paper, cardboard and lightweight craft materials. The single-stick format is convenient for office, school and hobby use, offering a compact, portable solution for everyday pasting tasks. The formulation provides quick tack and smooth application while keeping surfaces relatively free of residue.

Advantages

The Astra glue stick delivers even coverage without liquid mess, allowing precise application on edges and small surfaces. Its solid, non-drip composition reduces the risk of warped paper and excess soak-through compared with liquid glues. The twist mechanism protects the adhesive between uses and simplifies dose control, while the clear-drying formula helps maintain a clean finish on white and colored papers.

Suitable for

• Paper-to-paper assemblies such as school worksheets, envelopes and collages
• Lightweight cardboard and poster mounting
• Scrapbooking and general paper crafts
• Office tasks like attaching notes, labels and temporary fixes

How to use

Twist the base to advance a small amount of adhesive and apply directly to one of the surfaces to be joined, spreading evenly for full coverage. Press the glued surfaces together and hold briefly to ensure contact; allow a short setting time for maximum bond strength. Retract or replace the cap after use to protect the stick from drying out. For larger areas, apply in parallel bands to maintain even adhesion.

Usage recommendations

Use at room temperature on clean, dry surfaces for best results. Avoid applying to wet or heavily textured materials. For heavier or load-bearing bonds, choose a stronger liquid or specialized adhesive. Keep out of reach of children when not supervised and store upright in a cool, dry place.
