Thank you for viewing. This is a set of 5 Arita-yaki (Arita porcelain) lidded teacups by Matsunaga. I received these as a gift, but I haven't used them and have kept them at home. The box has deteriorated, but I believe the contents are fine. However, the inside of the box was red, and as a result, the underside of the teacups has become slightly red, so please check the photos. Although they are new and unused, they have been stored at home for a long time, so please consider them as used items before purchasing. Also, please understand that there may be some slight stains or dirt due to aging.
