I believe this was a novelty item from RONI. I have kept it stored in a cupboard since I received it, without using it. While I don't see any noticeable scratches or stains, please understand that this is based on my personal storage and inspection. Please only purchase if you are comfortable with this. 【Bulk Purchase Welcome!】 Bulk purchases are very welcome! Also, if combined shipping doesn't increase the shipping cost, or if it's cheaper than shipping individually, I will offer a discount! Please feel free to consult with me in the comments. #RONI #OnigiriLunchBox #OnigiriCase #OnigiriLunchCase
