Stamping Foam blocks

Simon Hurley Stamping Foam 3x4.25" - four pieces in pack.  Heat gently with heat tool, make impression with stamp, die, household items.  Ink up and use as stamp.  Clean, heat gently and it returns to normal.  Can keep impressions in foam, but the longer you keep them in, the less smooth they heat out.  Foam may stain with ink (as stamps do), but still works well.
