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 BM422 there are four full nail images and two smaller ones. All of the images were really easy to stamp. Of all the designs I like the chevron one the most, although the popcorn is really cute and I need to use it soon.
You can see all of the designs I have used this plate here, once I have used it!
