Rock A Blocks

I got some new toys yesterday! They are called Rock A Blocks by Crafters Companion. They are blocks to mount your acrylic stamps to. They are curved so that you get a better image with your stamps! They "roll" the image onto the paper making sure that every part of image touches the paper. I am fairly new to stamping and I have a real issue with this, there is always part of my image that is not a dark as the rest and I have tried everything, sanding, washing, erasers, nothing had worked-until now! I ordered mine from a local scrapbook store, but I know that PaperTreyInk also carries them. They sell for about $20 for the set of 4. The packaging says something about RockABlock adhesive, but my CTMH stamps stuck to the surface just fine.

Here is a close up of one of the blocks. See how the surface is curved and there is a little lip on each edge, so that only the image touches the paper.
