This is a Fire King stacking mug in yellow. It's a stackable type of mug. I purchased it at an antique shop in the United States. The size is approximately 7.8cm in diameter and 8.8cm in height. Although not easily noticeable, there are some paint loss and discoloration on the handle, etc. (photos 5-8), but it is in a beautiful condition with no cracks or chips, and with little signs of use. This item is in good condition with little use, but please consider that it was used in an American household. There may be some minor scratches and paint loss. Also, we may omit explanations regarding conditions that are believed to have been caused by manufacturing techniques at the time. Please ask any questions you may have before purchasing. Please refrain from purchasing if you are concerned about minor condition details. *We only accept price inquiries for combined shipping when purchasing multiple items.
