Simon Hurley's Stamping Foam is a moldable foam piece that may be used to make one-of-a-kind stamps. Heat the foam with the Heat It Craft Tool, then press it into any textured surface, such as stamps, stencils, and domestic surfaces. Simon Hurley collaborated with ink textured foam to create Dye Ink Pads. Two 4.5" x 5.75" rectangle foams with a removable heart measuring 3.5" x 3.125" are included, all with a 20 mm depth.
