This is the biggest yunomi we own, bigger than an Oestreich(as in Jeff, not the bird.) I bet the thing holds like 18-20 oz. Here is a shot of his cup, a mt dew can and what I consider to be a large yunomi of mine.
Today I took a bunch of pots over to a gallery for a small group show I'm in...I'll post photos when I'm allowed. I have some pots to handle and foot today so I'd better stop blogging and get to work.
