This is a cold tea set from Ishizuka Glass Co., Ltd. The size is approximately 7.7cm wide and 6.5cm high. The bamboo coasters are also unused, but there are stains and splinters due to long-term storage. The outer box is quite damaged because it was stored in a storage shed for a long time. Please refer to the images for the condition of the product. Please purchase with the understanding that this is long-term storage by a private individual. Please refrain from purchasing if you are sensitive to such matters. Immediate purchase is welcome.
