This paper glue that is blue when wet and clear when dry can be used in 2 different ways. For a permanent hold, apply glue to one paper surface and adhere it to another paper surface. For a repositionable hold apply it to a paper surface surface and allow it to dry clear. It is acid-free and safe for scrapbooking. It is also great for craft paper, glitter, embossing powders, foil and positioning stencils. It does not leave a residue.
