Two-Way Glue Pen. This paper glue that is blue when wet and clear when dry can be used in two different ways. For a permanent hold: apply glue to one paper surface and adhere it to another paper surface while wet and wait for it to dry; for a repositionable hold: apply it to a paper surface and allow it to dry clear before attaching it to another surface. This acid free and scrapbook safe glue is great for craft paper; glitter; embossing powders; foil and positioning stencils and it does not leave a residue. This package contains one Chisel Tipped pen. Made in USA.
