We love Castelli's Appeel notebook. Thanks to a patented and pioneering technique, it's made from apple peel, selected vegetable fibres and FSC-certified sustainable pulp. Not only that, the paper is manufactured using 100% green energy.

The cover is made from Frumat, a bio-based leather alternative made from Italian apple industry food waste; it's flexible but sturdy, with rounded corners. It features an elastic closure band, pen loop and fabric page marker in a contrasting colour. There's an inner pocket for stray bits and pieces, and coloured flyleaves. It measures a portable 130mm x 210mm.

Inside, there are 192 pages of Crush apple paper, which is made by the Italian company Favini. They replace 15% of the cellulose from trees with the process residues of organic waste - in this case, apple pulp. It's FSC-certified and has a ruled layout. What's more, the remaining carbon footprint is offset by a reforestation project in Kibale National Park, Uganda. In fact, it has everything you'd want in a notebook, without the damage to the environment.

And the colour names are very appeeling!

Castelli notebooks are proudly made in Italy with great emphasis on quality, environmental sustainability and extraordinary attention to detail.
