The rounds are machine washable at up to 60C. We suggest washing them in a mesh laundry bag, as this will extend the lifespan of the rounds.
The rounds are made of 70% Scandinavian wood fibers and 30% cotton fibers that are too short to be used in the textile industry. The case comes in two versions and is either made of a plant based material, or of recycled ocean bound plastic collected in Indonesia in collaboration with the organisation: https://www.reseaproject.com/.
Manufactured in Denmark.
