I'm not sure where I bought it, but I think it was either Nitori or Muji. I haven't used most of what I bought, and there are no noticeable stains or scratches. Due to shipping costs, I cannot lower the price any further. Since the thickness is borderline for Nekopos, I plan to ship via Yu-packet Post. Please feel free to comment if you have any other questions. Let's make this a pleasant transaction for both of us!
