This 5" x 6" acrylic stamping block is designed by Simon Hurley for Ranger Ink. This large acrylic block is 6 mm thick and has an excellent gripping edge. There is a 0.5" grid on top which allows for easy alignment and precision when stamping clear photopolymer and rubber stamps. The thicker printed lines in the center of the block act as a guide for accurate centering. This block can also be used with stamping foam, peel-apart rubber stamps, and photopolymer stamps (all sold separately).
