Feel Natural Refillable Toothbrush, Bamboo and Aluminium Handle

Why it is on the list

A screw-in head design lets you keep the bamboo and aluminium handle and replace only the head, cutting the amount discarded each time.

Watch out for

Castor-oil-based filaments are a bio-based polymer rather than a natural fibre, and replacement heads must be bought separately.

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.
