Blue Willow pattern coffee mugs, vintage Japan blue & white china ceramic cups

Vintage Blue Willow pattern coffee mugs made in Japan. This is a lot of two cups, not identical.

These have a heavy restaurant china shape, but are not as heavy as ironstone, they're a lighter weight china ware.

These mugs are about 3 3/4" tall, and are both in good clean condition, used but nice, without chips, cracks or noticeable staining.
