Colgate Bamboo Charcoal Toothbrush, Soft

Why it is on the list

A mainstream-brand bamboo toothbrush that is easy to find in shops and comes in a cardboard pack.

Watch out for

The listing itself says to put the brush head in the bin and compost only the handle, so the bristles are not a plastic-free part.

We have not physically tested these products. Our shortlist is research-based: we check what the listing says, favour non-plastic main materials and name the limits we can see. Always read the listing for sizes, certifications and care instructions.
