minimalist modern art design white porcelain cups or mugs w/ flat wave curved handles

Set of six unmarked white porcelain cups with finger grip handles, asymmetrical shape at rim.

I have no idea on the artist or manufacturer of these cups, but they're very eye catching and thought provoking in their modern design - and the plain glossy white keeps them classic.

They hold 6-8 ounces, and stand about 3 3/8" tall. All six are in excellent, unused condition.
