This is 100 sheets of WHITE Tomoe River (Tomoegawa brand) paper, printed with subtle 7mm lines, bound to a binder's board and protected by a fold-over red cover.
NOTE: As of 1/15/21 this is new Tomoe River paper!
The paper is the 68 gsm version, which is thin, strong and resists ink bleed-through and feathering (great for fountain pens). At the same time, it is sheer and delicate and crackles softly, like the pages of a dictionary. It is smooth but not slick, quiet, and will keep up with fast writers. If there were beauty contests for writing paper, Tomoe River would surely be a finalist.
