DTC brands citing packaging as a top-3 cost61%

Brands want to ship sustainably, but compostable packaging today is either too expensive to scale or too flimsy to protect the product.

The solution

A mycelium-based mailer that composts at home in 45 days.

Grown, not manufactured — Arbor mailers are cost-competitive with corrugate at volume, and break down in a home compost bin, not just an industrial facility.
