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 BM426 there are no full nail images and eight smaller ones. All of the images stamped across, other than the V which was a little trickier. I have used this for both Valentine's Day nails as well as in other letter nails.
You can see all of the designs I have used this plate in here,
