Nine notebooks in the practical 90x140mm size - perfect for pockets and bags, and also suitable for many notebook covers. Dot-grid, with 36 pages of FSC-accredited 110gsm paper.

There's one book for each planet, plus one for the sun, so you can work your way through the solar system with your notes. When you reach Neptune, and run out of notebooks, you can blame the International Astronomical Union for downgrading Pluto - you'd have an extra notebook if poor Pluto hadn't been demoted. They're scaled, so while Jupiter doesn't all fit, even across front and back covers, our own rather nice blue ball looks rather small - a regular reminder of either our own insignificance or the spectacular scale of the world we find ourselves in.

The designs are all quite beautifully minimalist in style, and the inner covers give information about each planet and the sun, and a reference page explaining the units used. Planet names are embossed with silver foil on the front.

Covers printed on 300gsm card.
