This is a takoyaki (octopus ball) mug by Ari Kurihara of Nogasha. It's a one-of-a-kind, hand-painted and hand-formed piece. I purchased it about 5 years ago. I've kept it in storage without using it, but I'm selling it now because I have too many dishes. As it's handmade, there may be kiln marks, uneven glaze, and crazing. Please refrain from purchasing if you are looking for a perfect item. Thank you for your understanding regarding home storage. I will carefully pack and ship this as it is a fragile item.
