I purchased this new, but I mistakenly thought it was 13cm, so I'm putting it up for sale. I thought it would be good for zenzai (sweet red bean soup) or clear soup, but I've never used this size before and don't think I'll get used to it, so I'm offering it for sale. I have washed it once. Please note that there is a scratch as shown in the fourth photo. I have been using wooden soup bowls for many years, and this is a series that lasts a long time and is very comfortable to use.
