• Recycled cellulose sponges are 100% biodegradable and made out of renewable resources (wood pulp & cotton & recycled beer bottles) • Natural colours with no added pigments
I really like the fact that this product is dye-free. However, before I make a purchase, I would like to know more about the "natural aniti-microbial technology" applied to this product. Is nano-technology being used? Thank you.
