Yunomi #40 is soda vapor fired earthenware with a draining straw to discourage overfilling.
Online shopping is tricky since you can't try something on to see if it fits. I want to be clear with my supporters that I don't concentrate on the functional aspect of the pieces. None of the cups are intended as an ergonomic fit and I sacrifice the function for the fiction. Like an ancient broken or damaged relic, I encourage the viewer to explore and question the potential function of each piece.
