A5 Nucleus
A handmade leather A5 notebook cover designed to keep your tools for thinking in one place.
The Nucleus is built around a simple idea — a notebook, pens, and essential papers, held together in a single piece that can be opened, used, and packed away with ease. Cut and assembled in my workshop using full-grain leather and solid brass fittings, it is made to be used daily and to improve with time.
It rolls open to reveal space for an A5 notebook, with integrated storage for pens, notes, and small items. When closed, it becomes a compact, structured piece that carries easily and keeps everything contained.
Simple, practical, and built to last.

The A5 Nucleus combines beautiful, tactile materials with Neil’s exceptional leather craftsmanship. Warm and supple in the hand, it reflects care and precision in every detail. A pleasure to open, hold and write in, it already feels like a companion that will gather ideas, notes and memories over time. Thank you, Neil, for creating such a thoughtful piece.
