Kirjoituslehtiö Sigel CONCEPTUM A4 160 arkkia musta

The CONCEPTUM® spiral notepad combines a durable hardcover and double metallic spiral to create a robust, professional writing pad. The A4-format squared pages (approx. 24.6 x 30.1 cm) lie flat when opened thanks to the sturdy spiral; each sheet is microperforated for easy removal and made from chamois-coloured, 80 g/m² PEFC-certified paper. The notepad includes a removable two-colour plastic index, 4-hole punching and a quick pocket for loose documents.

Advantages

The hardcovers and double metallic spiral ensure long-lasting stability and a flat writing surface. Microperforated pages allow clean tearing, while the blank side margin and date field at the top of each page support organised note-taking. The insertable plastic index makes it easy to mark and access sections.
