Rollbahn by Delfonics Classic A5 Spiral Notebook

Delfonics' Rollbahn has been around since the early 2000s, and it's one of those notebooks a few of us already owned before we ever started selling it.

The spiral-bound cover is thick enough to write on without a flat surface underneath, and each page uses smooth, wood-free paper that resists ink bleed-through. It comes in a 5mm cream grid, with perforated pages and five clear pockets built into the back cover for loose receipts or cards. This A5 size runs 80 pages.
