Thank you for viewing. This is a set of 5 square plates featuring blue birds, made by Mino ware artist Shouzan. The size is approximately 13.5 cm in diameter. I received these as a gift, but I haven't used them and they've been stored in my home warehouse. The box is deteriorated, but I don't think it affects the plates themselves. However, please understand that there may be some slight stains or dirt due to aging. 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.
