Penscore foam is used to make your own stamps by heating the foam to 300 - 400 degrees F for about 30 seconds and then quickly pressing it onto a 3D object or any dimensional surface to create texture or an image. The image will remain until the foam is reheated.
Use with water based ink pads, markers or paints pads to stamp with your image. Wash with water to clean the foam. You can reheat the block to remove the original impression. Deep impressions may not come out until you actually remold with another object.
