This is a valuable set of calligraphy ink commemorating the change of era from Heisei to Reiwa, released by Bokundo to celebrate the new era (a set of 2 inks: Reiwa and Heisei). Perfect as a commemorative item or gift! An elegant crane design is engraved on the back. (See photo 3) The ink is made from soot (pine smoke and oil smoke) and glue. It comes in a paulownia wood box. This is a high-quality ink sold at stationery stores for a regular price of around 12,100 yen. Diameter: Approximately 7.5cm Thickness: Approximately 1.3cm I opened the box once for photography, but it has been stored unused since then. The ink is wrapped, and the wrapping has not been opened. It will be packaged with bubble wrap for shipping. Seller Information: Smoker: No Pets: No #Ink #Bokundo #EraInk #Calligraphy
