This Ultra Sticky Mat: Grid is from Altenew. This mat is for use with the Stampwheel (sold separately) also from Altenew. This mat features an etched grid for easy alignment in the Stampwheel. This mat is much more tacky than the original mat, making it strong enough to hold heavyweight cardstocks up to 110 lb and/or watercolor papers. This mat is made from clear photopolymer and cleans up very easily. When using dark colors, just like stamps (sold separately), this mat may stain, however, will not affect the use of the mat. To keep your mat sticky, occasionally remove it from the Stampwheel and wash it under running water, and also rub the dust off while rinsing. This mat is made in the USA.
