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 BM404 there are four full nail images and two smaller ones. I like the designs but because of the intercicity of the designs you have to be so quick with your stamping that is can be hard to wok with.
You can see all of the designs I have used this plate in here, and some of those are below:
