Delfonics is a Japanese design firm known for impeccable quality, thoughtful form and one of the best color palettes in stationery.
This notebook has a very heavy cardstock cover that shrugs off the occasional raindrop, fountain pen-worthy grid paper -- lightly rendered for note-taking versatility -- five useful cellophane sleeves bound into the back and an elastic closure. Spiral-bound to lay flat when that's important. Perfection.
