I bought this plate in August 2018, about time I reviewed it! It came backed with thick white plastic which means no cuts from sharp edges, also protected by a blue sticker. It may have also came in a cardboard slip but I forget as it was three years since I bought it.
It is rectangle and designed for longer nails which works well for me. I have found all of the images stamped across well in the various nail art I've done with the plate.
