The handle is made of natural bamboo sealed with an edible wax. The bristles are soft to medium stiffness, with sharpened bristle. The toothbrush comes packaged in a sealed recycled cardboard box.
When you have finished with your toothbrush you can put it to another use, cleaning your bike or intricate objects. Climbers you could use it to clean holds. If it falls out of your pouch and you loose it, no guilt, it will disappear over time in the natural environment.
Stick it in the compost and it will go eventually. My favourite method to date is to nail it vertically into the lawn, gone!
