There is a dragon-carved pattern on the back. I don't have any knowledge of calligraphy, but it came up while I was organizing my belongings. There's a little black ink on it, but it's hardly been used. Perhaps someone did a test print. Someone may have bought it to draw with. It seems to be quite old, as Eijudo no longer makes them. The price sticker is from before the consumption tax was introduced. I've priced it based on other listings. - Color: Blue ink - Decoration: Blue characters and carving - Design: Dragon carving - Size: Approximately 8cm x 1.8cm x 0.5cm Thank you for looking.
