Such and easy one to answer, that would have been Model's Own Speckled Collection, I've managed to get a couple from the collection but there are still a few eluding me!
Another plate I don't remember when specifically I bought it but it was in 2020.
The stamping plate comes with a blue protective layer which you peel off and branded backing. It is a large plate measuring at 145mm by 950mm.
The majority of the images on this plate are designed for Halloween and spooky season as a whole. All the images stamp across well, and the engraving works fine.
