This stamping plate is from the forth Bundle Monster set, the first CYO (create your own). It is backed with branded lining to stop it from being sharp, comes covered with a blue cellophane sticker which you have to peel off before use.
On BM413 there are six small images. I really like this plate, lots of sugar skulls and skeletons. Very Halloween appropriate. I had problems getting the delicate skull cluster across, again working quickly helped.
You can see all of the designs I have used this plate in here, and some of those are below:
