1. Choose Your Cover
Pick the size that matches the notebooks you already use. Elastic bands hold 2, 3 or 5 notebooks depending on the model — the cover stays, the paper changes.

2. Add the Extras
Covers ship without paper, so start there. Then add a zip pocket or leather organiser, and a charm if you want one.

3. Make It Yours
Add initials, a name or your own artwork on the product page. Gold or silver foil stamping, blind debossing, or laser engraving — chosen before you add to cart.

Before

After
You can find all available options in the product features — including elastic color, cover color, and personalization (stamping or engraving). Simply choose your preferences on the product page to fully customize your notebook cover.
Laser Engraving
A laser beam etches designs, patterns, or text into the leather surface — precise customization and branding.
Stamping
Designs are impressed into leather with metal stamps and a thermo press.
Colored Stamping
Heat-resistant foil transfers metallic gold or silver onto leather through heat and pressure (hot / foil stamping).

Every cover is made by hand: we mark the pattern, cut and prepare the leather, assemble the cover, stitch it, and finish the edges. The hide is wax-impregnated Crazy Horse leather with a pull-up effect — the colour shifts where the leather flexes.
The cover ships without paper. On the product page you can add a lined or white refill in all eight sizes, or shop paper refills on their own.
