The Zig 2-Way glue is blue when wet and dries clear so you can see where you applied it! For a permanent bond, attach your papers and other items while the glue is still wet. If you just need a temporary bond, apply the glue lightly and use it after it dries. The glue is acid-free and xylene-free. Perfect for thin or tiny die cut shapes, sequins, or other small crafting elements!
