Questions?

How can I customize my packaging?

You can easily make each box fit your brand’s style:

  • Luxury box: Choose between classic brown or sleek white. The size of the mycelium inlay is fixed and you can customize the entire box with your own branding.
  • Mailer and E-commerce boxes: These come with two different sizes of mycelium inlays—large or small. You also get to design the paper components that wrap around the box.

What are the differences between the Mailer Box and the E-commerce Box?

The Mailer box is designed with a dual-part structure that encases the product. It’s held together with a customizable paper component.

The E-commerce Box, on the other hand, offers the same inlay configuration but in a single-piece box .

Both boxes show the mycelium inlay, for a natural look.
