A quite lovely cylinder. It's porcelain with sometsuke (underglaze blue), and I'm not sure if it was intentional, but the cobalt glaze has run, which gives it a nice feel. There are scratches, stains, and minor imperfections consistent with its age. Diameter: Approximately 6cm Height: Approximately 4.9cm Sizes are approximate. The actual item may differ slightly in color from the images.
