This is a Sumi-e ink stick, "Ankyo Rakugyo" No. 59 from Bokuundo's Hyakusen-boku series, 8-cho size, made with pine soot. The ink color is a subdued blue-black. It has been stored at home since I acquired it. The film was removed for the photos. It is in very good condition. This ink is still sold today, with a retail price of 49,000 to 55,000 yen. # Click here for a list of calligraphy works and tools from Oak 77 # Click here for a list of ink from Oak 77 Size: 10.2cm x 6.5cm, thickness 1.2cm 8-cho size (108g) #ink #Bokuundo #Hyakusen-boku #Ankyo Rakugyo #PineSootInk #BlueInk #calligraphy #Japanese_inkstick
