Our acrylic mounting blocks are high quality.
1/2 inch (1cm) thick, Rounded edges and corners.
With Cling stamps you really only need a couple of acrylic blocks because they are reused over and over again.
Peel your Cling stamps off their clear backing sheet and position it on a clear acrylic block. The Cling foam makes it possible to temporarily stick or "cling" to the block. This process makes it easier to see where you are stamping. When finished stamping, just peel your stamp off the block and return to the backing sheet or whatever you are using to store your cling stamps. We recommend using CD jewel cases, just take the round CD part (usually black) out.
