This is a mug by Shiyu Nakaoka. I received it as a gift, but I'm not going to use it, so I'm offering it to anyone who likes it or collects merchandise. I took it out of the box for the photos, but I haven't taken it out of the inner bag. I'm not sure how much it's worth, so I've set the price at this level for now. Please feel free to contact me to discuss.
