I believe this is a classification of hard plastic. I've used it a few times before, so there are some scratches, but in my amateur opinion, it's still usable. Please consider purchasing with the understanding that it has been stored for a long time. 【Size】(Approximate) 10cm x 10cm, Thickness 3mm There is no dedicated box, but I will wrap it in bubble wrap and send it via Yu-Yu Mercari's anonymous shipping service after purchase. Returns are not accepted due to the inconvenience of shipping. Thank you for reading to the end.
