The handle The handle is made of MOS bamboo, an environmentally sustainable timber. The bamboo is heat treated to carbonise the surface of the bamboo, giving it a quality finish and good service life. The carbonisation finishing process provides water resistance and prevents the growth of microbes (bacteria and moulds) during normal use

The bristles 1. The bristles are made from 100% biodegradable soft and medium bristle, nylon4, bamboo fiber, or corn fiber. 2. We recommend you rinse and dry your toothbrush after use to keep it clean.

Disposing of your toothbrush 1. For best results, most dentists recommend you replace your toothbrush either monthly or at least every quarter some even say use it until it stops.

2. To answer the main question, HOW LONG DOES IT LAST? - We test drove a toothbrush for over 8 months so yes they last (not that we suggest you do that).

3. The Environmental Toothbrush can be disposed of safely by returning it to earth in compost or landfill. Both the bamboo and bristles will biodegrade into soil, without pollution.
