I purchased this item as an old piece from Fujina (布志名), but I cannot definitively confirm it as 100% authentic. However, I believe it is clearly older than later yellow-glazed pieces. It appears to have been well-used. It feels good in the hand, and the green of the matcha beautifully complements it. As it is an old piece, there are age-related scratches and stains, a thin crack (nyu) visible in the image, and what appears to be an adhesion mark near the foot. Diameter: Approximately 13.5cm Height: Approximately 6cm Sizes are approximate. The actual color may differ slightly from the images. Please examine the description and images carefully before purchasing.
