The Go Bamboo toothbrush comes in adult and child sizes. The handle is made of natural bamboo (not a bamboo laminate) sealed with an edible wax. The bristles are soft to medium stiffness, dual length, sharpened bristle, made from nylon 4 activated in sewage or compost, nylon 4 breaks down in about 3-4 months) and they clean your teeth really well. The toothbrush comes packaged in a sealed recycled cardboard box. Disposing of your toothbrush, stick it in the compost and it will go eventually. A favourite method to date is to nail it vertically into the lawn, gone! No guilt disposal!
