This Low Tack Sticky Mat: Grid is from Altenew. This mat coordinates with the Stampwheel (sold separately). This mat is less tacky than the original Sticky Mat and features an etched grid for easy alignment. To use, this mat should be removed from the acetate sheet. It should be placed inside the Stampwheel with the engraved side down, flat side up. This mat is made from photopolymer and certain inks will stain it. If needed, you can place scrap paper where you are stamping to catch the ink on the edge of your project. This mat should be kept clean by washing it under running water. The dust should also be rubbed off of it if you leave it in the Stampwheel. After you wash it, let it air dry. This mat measures 7.5" x 7.5". This mat is made in the USA.
