## Summary description

sigel Conceptum CO640 is a DIN A4 squared notebook with beige Softwave-structured hardcover. It features squared (grid) pages suited for notes, sketches, technical drawings and planning. The hardcover provides durable protection and a premium tactile surface; ideal for office, study and project work where precise layout and robust binding matter.

## Long description

sigel Conceptum CO640 is a DIN A4 (approx. 213 x 295 mm) squared notebook with a beige Softwave-structured hardcover and 194 pages, including 20 perforated pages. The squared (grid) pages are printed in grey on chamois-coloured paper (80 g/m²) and the book includes an elastic fastener, a pen loop, two ribbon markers, a quick pocket and an archive pocket. The hardcover’s rippled soft-touch surface provides a firm writing surface and a tactile finish suitable for office, study and project work.
Advantages
The squared layout supports precise notes, sketches and diagrams while the sturdy beige hardcover protects contents during transport and daily use. Perforated pages enable quick removal and sharing of notes, and the elastic fastener plus pen loop keep tools and pages secured. Numbered pages and a personal directory help with organisation and quick reference.
Suitable for
Technical sketches and drawing with grid guidance
Project planning, task lists and structured meeting notes
Study notes, formulas and tabular data
Design mock-ups and hand-drawn layouts
Everyday office documentation and journaling with organised indexing
When it may not be suitable
Because pages are squared, the notebook is not ideal for long-form prose where lined or blank pages are preferred for continuous writing. Users who require acid-free archival paper or very high-weight art paper for heavy ink or wet media may find the 80 g/m² paper weight limiting.
