Delfonics' Rollbahn Notebook is a perpetual staff pick at Milligram, and one of our all-time favourites. The notebook's durable spiral-binding is extremely well-made, combining beautifully with a robust, splash-proof cover. The Rollbahn notebook features high-quality, fountain pen-friendly paper, and each page is perforated for clean removal. The grid ruling (5mm x 5mm) makes this notebook simple yet versatile, perfect for design, planning or everyday writing. It also features an elastic closure strap, and 5 internal pockets to hold loose pieces of paper, notes & receipts.
