Simon Hurley create. Stamping Foam are moldable foam pieces that are great for creating original and unique stamps. To use, heat foam with Ranger's Heat It Craft Tool. Then, press foam into a textured surface and hold in place for 5-10 seconds. Now ink the stamp you just made. The foam can be reheated and remolded to use over and over again. Available in a 4 piece pack, each measuring 3 in. x 4.25 in. with a 20 mm depth, and a 2 piece pack, both measuring 4.5 in. x 5.75 in. with a 20 mm depth.
