The EK Success® 2-Way Glue Pen gives you the option of permanent or repositionable adhesive. The glue is blue when it's wet and clear when it is dry, which allows for perfect positioning of a thin line of glue exactly where you need it. It's great for cards, scrapbooking, gifts or any other paper crafts, including adhering glitter, confetti, foil, sparkles, and more. For a permanent bond, use when wet (blue). Let it dry clear for a temporary, repositionable bond. It is non-toxic, acid & xylene-free adhesive. Measures .35 oz.
