FSC stands for Forest Stewardship Council, which is an international non-profit organisation founded in 1993 with a mission to create responsible forestry. It is the only forest verification scheme endorsed by leading environmental charities like WWF, the Woodland Trust and Greenpeace.
You can find the FSC logo on YES products, certification means that our card and paper components (i.e. cartons and Instructions for Use) are made with materials from well-managed forests and/or recycled sources.
