Bottle brush made of 100% biodegradable materials.
The materials are "wastes" of, for example, the coconut industry.
No packaging, only one label made of recycled cardboard.
For each brush sold, a tree is planted.
Zero Waste Club is a small British company run by two students who work closely with production companies abroad. They care about the workers and the environment. In addition, they are very transparent and do not shy away from answering any questions.
