EZMount Haftschaumstoffplatte 8,5 x 11"

The adhesive side held my rubber sheet firmly in place without any shifting, and the cling side grabs my acrylic block cleanly every time. Cut it to size with scissors easily, so trimming down for smaller stamps was no trouble at all.

The cling side grips my acrylic block firmly with zero sliding, and the adhesive on the back held my rubber sheet perfectly after a few firm presses. It's thin enough that my stamps still line up precisely, which is exactly what I needed.

I was a bit skeptical about the adhesive holding my rubber stamps, but after pressing them down they've stayed perfectly in place for weeks now. The static cling on the other side is a nice touch—lets me swap stamps between blocks without any residue.
