Allows you to make any rubber stamp into an EZMount stamp that clings perfectly to an acrylic block. No sticky mess and never wears out. It is not recommended you store any of your EZMount stamps on acetate sheets. Acetate is made with chemicals that react with EZMount and other cling cushion type product, making it almost a permanent bond between it and the cling. Sheet size has now been increased slightly more than A4 size which is great as you can fit on so many more stamps/sheets. Sheet size 21.5cm x 30.0cm (8 ½" x 11 7/8 inches)
