"Imagination leads us to all we might yet discover and create." That quote is part of the feature stamp in Tim Holtz's Nature's Discovery rubber stamp set. These stamps will let you use your imagination to discover and create. Each of the five stamps are made from rubber with a foam backing. To stamp, cling mount one to an acrylic block (not included). They can be stored on the included storage sheet, which is three-hole punched and measures 7" x 8 1/2".
