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.
With BM415 you get four full nail images and two smaller ones. The plate is geeky and has a steampunk image to which is nice. I found the word search image and the binary numbers hard to stamp across fully.
You can see all of the designs I have used this plate
in here, and some of those are below:
