We offer it in a few commonly used sizes, so if you’re making standard notebook formats, it’s pretty easy to choose what fits your project. The blade is made from Japanese steel, so the cut comes out clean and the size stays consistent, which is especially helpful if you’re making more than one piece and want everything to match nicely.

Available sizes:

Large: 15.5 × 22 cm
Standard: 12.5 × 22 cm
Portable: 11 × 17.3 cm
Passport: 10.5 × 13.5 cm

The wooden notebook covers shown in the photo are just there as a size reference, so you can get a better feel for how each format looks in real life.

We can also make this as a custom die if you already have your own size or design in mind. Both wood base and acrylic base versions are available.

If you’d like to customize one, just email us your size, design, and the material you plan to cut, and we’ll take a look with you.

Please note that dies are consumable tools and will naturally wear over time. It’s a good idea to clear away any waste material after each use to help avoid clogging. Each die has its own working lifespan, so for everyday care, please try not to leave it in a damp environment, avoid scratching the blade during handling, and keep it out of reach of children.
