Tohma Kumataka 55 Art Collection Raden Shunko-sai/Black Fountain Pen
Handmade in Japan by master craftsman Kiyotaka Tohma, the Kumataka 55 in raden is a pen that demands attention.
Crafted from deep black ebonite and inlaid with vertical bands of luminous raden (mother-of-pearl), each piece is a singular work of functional art.
Fitted with an 18kt Tohma 3mm wide calligraphy nib with 3 slits x 4 holes, made in-house and engraved with his workshop mark. The ink filling is “Type B” with a built-in fixed snorkel pump filler that does not require the entire nib to be immersed in ink. The ink capacity exceeds 6cc.
Finished with subtle black trim and a gold signature on the cap, the design lets the shifting colors of the raden take center stage—elegant, precise, and unlike anything else.
