With the exception of one head, everything changes for the planet so have Le Clic and adopt a toothbrush with a rechargeable head. The easiest zero-waste gesture to adopt! Every 3 months you simply change your head and keep the handle for life. - Each handle is composed of 98% polyamide derived from castor oil. It is then colored with a vegan dye. Everything is made in France, even the mold! - Each head is composed of an ABS (Acrylonitrile Butadiene Styrene) base, a thermoplastic that is ultra-resistant to shock and humidity, a metal ring and bristles. These bristles are made of nylon for soft and medium heads, or polybutylene terephthalate (PBT) for extra-soft heads. Both nylon and PBT allow our toothbrush bristles to regain their shape after brushing. Everything is made in France.
