Burgundy Mycerra pure mycelium mat, dyed three times, curling to show its grain

100% pure mycelium · grown in Korea

Grown,not manufactured.

Mycerra™ is the leather alternative made exclusively from pure mycelium — no backing, no scaffold, no plastic.

A 100% pure mycelium mat that is finished to the same standard as premium leather — and returns to the earth at the end of its life.

What we make

A material, not a laminate.

Mycerra™ uses no non-woven backings, scaffolds or foreign substrates. The mat is the material — cultivated, stabilized and finished.

Material library

Why it matters

Sustainability with proof, not promise.

−92% greenhouse-gas emissions versus animal leather, no animal inputs, and every batch origin-tracked for EUDR compliance.

Impact & evidence

How we do it

Biotechnology and design.

Uniform growth under ambient conditions, then a proprietary stabilization step that gives the mat leather-grade strength and handfeel.

Technology

Material library

One mat, many expressions.

The same cultivated mat takes aniline dyeing, crocodile and caviar embossing, or stays as a raw natural surface.

From cultivation to finish

Three steps. One material.

Cultivate

Cultivate

Mycelium is grown into a continuous, self-supporting mat in controlled facilities in Korea — no backing fabric, no scaffold, no foreign substrate in the final material.

Stabilize

Stabilize

Where hides are tanned, Mycerra™ is stabilized. A proprietary process turns the cultivated mat into a durable material, defining its strength, flexibility and handfeel.

Finish

Finish

Like premium hides, Mycerra™ takes aniline dyeing, embossing and protective finishing — from a raw natural surface to deep, three-times-dyed colour.

Impact

Less water. Less waste. More balance.

99%

Biobased carbon

Radiocarbon (C-14) analysis shows that 99% of Mycerra™'s organic carbon comes from living biomass, not from petroleum or other fossil sources.

−92%

Carbon

Greenhouse-gas emissions compared with conventional animal leather manufacturing.

99%

Less water

Up to 99% less water than conventional methods, with no animal inputs.

0%

Plastic

No synthetic polymers, non-woven backings, scaffolds or composite layers.

100%

Compostable

Fully biodegradable at end of life.
