【Acquisition Date】 I got this at a Kura Sushi location that had a collaboration with "Chikawa" around the summer of this year. 【Storage】 I have kept it stored in a dark place. 【Scratches, Stains, etc.】 There was a little bit of dirt, but I removed it with a wet wipe. Since the surface is plastic, there was no damage. There are fine scratches characteristic of plastic products, but they are not noticeable. If you would like photos from various angles, have any questions, or would like to purchase this item, please leave a comment.
