Brush Naked Toothbrush with Biodegradable Bristles (Adult)
The 100% biodegradable, plant-based bristles are made from corn and tapioca and will LAST FROM 2 - 4 WEEKS. Stiffer than nylon bristles. (The 'softness' of the bristles is actually determined by the diameter of the bristle without any consideration for the material it's made from.) Naturally anti-bacterial and anti-microbial.
