The EZ Mount Stamp N Store is the ultimate mounting foam for stampers. The foam is specially-engineered to ensure it bonds with the rubber stamp permanently. It's so EZ to do! Just pull the blue liner that comes over the edge for easy application, then place your unmounted stamp on the super sticky foam. Never mount a stamp again. The other side of the foam sheet features a static cling surface. It will create a good vacuum seal between your stamp and the acrylic block. In each package, you'll receive one 8.5" x 11" sheet, which is 1/8" thick.
