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 BM412 there are three full nail images and three smaller ones. The cat image is so cute! All imaged stamped well other than the owl which I had to work quickly to stamp across.
You can see all of the designs I have used this plate in here, and some of those are below:
