Tomoe River paper is a silky smooth ultra thin paper that performs great with fountain pens. The nib glides across the paper with hardly any feedback. The ink develops its full colour and sheens appear effortless. Since the Japanese manufacturer Sakae Tomoegawa was overwhelmed by the ever-growing demand for the ultra-thin Tomoe River paper, they have sought a partner to shape the Tomoe River brand. Today Tomoe River is not only the name of a special fountain pen friendly paper but also a real brand with notebooks, writing pads, and loose sheets of paper.
