Made with Tsubame's elegant cream fools paper*, each memo block consists of 400 pages with a thick cardboard divider at the 200 page mark (so you can easily split the block in half to create 2 blocks of 200 pages each).  Paper size 3.35" x 3.35" (85mm x 85mm).

Choose: ruled, grid, plain, dot grid, "to do" or genkou (squared 'manuscript' paper ideal for writing one character or punctuation mark to the square - for example, when writing in Japanese).

*Fools Paper (or OK Fools) is a high-end Japanese writing paper, famously used in Tsubame's notebooks - it's designed to be exceptionally smooth yet fast-drying for fountain pens. Originating as a superior alternative to imported British Foolscap in the 1940s, it is known for being non-feathering, bleed-resistant, and having a slightly cream color that is easy on the eyes.
