From the manufacturer:
The perfect tool for deactivating the adhesive on part or all of a sticker. Also great to use before heat embossing; it ensures the embossing powder sticks only to your ink so you get clear, crisp images every time. The material in this tool deactivates adhesive on the back of stickers to expand the creative possibilities. Add dimension to your project using 3D-dots or add pins back or clasps to create accessories. This package contains one Powder Tool Applicator with 0.6oz of powder. Imported.
