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 BM405 there are four full nail images and two smaller ones. I like the designs and they all were easy to work with other than the droplet image, again I think I need to work on my technique with larger engraved images.
You can see all of the designs I have used this plate
in here, and some of those are below:
