Rustic handmade studio pottery stoneware noodle bowls or handle-less tea cups

Rough handmade and signed tea cups or rice / noodle bowls set, all in excellent condition.  There's eight pieces, all 3 1/4" across the rim x about 2 1/2" tall.

We don't know anything of the maker, or the exact vintage of this set, but we love it's wabi sabi feel, and rustic character.
