"Iroful" means "colorful," substituting the English word "color" for the Japanese word "iro." Accordingly, this new paper from Sakae TP—the originator of the hugely popular Tomoe River paper before its move to Sanzen—aims to bring out colors' full depth and vibrance with crisp lines and excellent shading and sheening for fountain pen inks. Iroful paper has a somewhat soft feeling and slight texture, and the 75 g/m thickness reduces ghosting and showthrough.
