Production
Iben Lea produces her ready-to-wear garments in Portugal, working with a family-owned agency named MCPR. She only produces small quantities, and all the products are made with fair labour.

Organic Cotton
It is grown within a rotation system that builds soil fertility, protects biodiversity, and is without synthetic chemicals or GMOs. Growers must meet organic agricultural standards set nationally.

The supply chain
Iben Lea's commitment to responsibility expands to trims and packaging, where she uses recyclable, plastic-free, and biodegradable materials. She always aims to create the lowest environmental impact possible.
The garment bags are made from curbside-recyclable FSC™ certified paper. These bags are from https://www.vela.eco/

Care 
Make sure to follow the care instructions on the garment - to ensure you handle it in the best possible way - this will make it live longer. 
A pair of undies have an average number of wash cycles of around 30. Twice as many uses per garment life-cycle eliminated almost 50% of the negative environmental impact.

Recycle
What should I do with my underwear at the end of their life?
Recycle as much as possible, but for underwear, especially panties, that's not really an option — Iben Lea encourages you to donate it to your local recycling facility.
