Postalco notebooks are extraordinary in form and function and highly treasured by lovers of Japanese notebooks. Starched, pressed cotton, treated for water-resistance, is bonded to heavy paper covers, steel spiral binding is positioned so that the spine of the notebook can be easily labeled, angled corners are a nice design touch. The craft of the Japanese paper maker is evident inside with pages lightly-textured to maximize each stroke of pen or pencil and printed with Postalco's calm-blue 1mm Pin-graph paper that guides linear writing yet is too fine to be obtrusive.
