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 libraryWhy 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 & evidenceHow 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.
TechnologyMaterial 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
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
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
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.
