This stamping plate is from the third Bundle Monster set, from 2012. It is backed with branded lining to stop it from being sharp. This is useful, without it it is easy to slice open your fingers and palms which I have been known to do accidentally in the past with other stamping plates.
BM324 is a french tip plate, I haven't really used these. However they all did stamp well.
You can see all of the designs I have used this plate in here, and some of those are below.
