This Squeeze & Roll Kuretake Zig 2-Way glue pen meets all of your paper crafting needs. The glue is blue when wet and dries clear. 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. This is like a Ball Point Pen style tip.
