The Bank Green A6 Pingraph Notebook from Postalco has been a standard in the lineup since 2004. These spiral-bound notebooks open completely flat for flexibility. The metal binding is partly covered, giving space to label the spine so you can stay organized. Starch-pressed cotton is bonded to the cover. The colors will lighten with use and the weave of the fabric will become more apparent. The fabric is water-resistant treated. The paper inside is Pin-graph, Postalco's original 1x1mm blue graph paper. It has a texture that keeps the pen from slipping too easily, making it an ideal writing surface to keep thoughts flowing. Suitable for writing or drawing. The page thickness prevents most show-through and the paper is ecologically made and chlorine-free. 4.3 x 5.8 in.
