Vihko Sigel CO309 A5 194 arkkia musta

The Sigel CO309 A5 writing notebook combines a flexible black softcover with 194 pages of high-quality 80 g/m² dot-ruled paper in a compact 13.5 x 21 cm format. The matte, slightly rippled cover feels pleasant to the touch and protects pages while allowing the notebook to slide easily into a pocket or bag. Practical features include an elastic fastener, an elastic pen loop, 20 perforated pages for easy removal, and a personal directory for quick page referencing — suitable for everyday note-taking, sketches and organised record keeping.

Advantages

Dot-ruled 80 g/m² paper supports neat writing and light sketching without significant bleed-through. An elastic fastener keeps the notebook closed, while the integrated pen loop ensures a writing instrument is always available. Perforated pages enable simple removal and sharing of notes, and the personal directory helps maintain an organised page index.
