Arita-yaki (Arita porcelain) Ichii Toen Gama (Ichii Kiln) Coffee Cups Set of 6 Thank you for viewing! These were in the countryside, so I don't know the frequency of use, but they look quite clean. Please check the photos. I am selling these to declutter. Immediate purchase is OK. Please refrain from cancellations or returns after purchase. I will sell these to those who understand that they are used items and have been stored at home. I will pack them carefully to prevent breakage during shipping. Thank you very much.
