I love this product because you can reuse it over and over. I think it works really well and is easy to use. I would suggest getting at least 2 of them and cutting the sheets into sizes slightly smaller than the acrylic blocks you have.
Works really well....holds the stamps on and is re-usable!
I was really excited to use this, it's a great idea for those who don't want to wood-mount their unmounted rubber stamps. However, the clingy surface was so sticky, that when I stamped on my LO, the exposed clingy surface got caught on a nearby photo so strongly, that it ripped the photo as I tried to pull it away. I would recommend this product only for small stamping blocks, not larger ones, to avoid what I encountered. I'm not sure if I'll continue to use this with my 4x6 acrylic block.
