This dual action permanent and semi-permanent ZIG Memory System 2 Way Glue pen is ideal for all your paper crafting projects.
With the Acid Free quality it is great for working with your precious photographs.
For permanent use, use immediately after applying the adhesive to paper and photographs. This is when the glue is blue.
For semi-permanent use, use when the adhesive becomes tacky. This is when the glue is clear and you will find that your paper and photographs can be repositioned.
