I bought this myself in Spring 2021.
The stamping plate comes in a plastic slip to protect it from scratches, it is backed with branded backing. It is 60mm by 90mm. Having used this plate a couple of times all of the images I have tried to use have stamped across well.
Some nails I've done using the plate;

|[Tarot Card Nails]|
