Japanese Espresso Set from Arita Japan, Hand Painted- set of 2

Gorgeous Artita Japan porcelain espresso cups and saucers, hand-painted, showcasing traditional Arita ware techniques, vintage. TINY chip on bottom of one mug & tiny stain inside same mug. It feels like this is from manufacturing, or maybe use & age, not really sure.. No other issues! Absolutely beautiful vibrant set! See pics
