We use wild organic bamboo. After cutting a large bamboo stock It will have new stock grows back to around 65FT within 2 years.
Bamboo stocks are boiled in pure water, dried, heat treated, carved and a natural wax coat applied.
Bristles are pressure implanted into each hole.
Switching to BAMBOO makes total sense!
Our bamboo toothbrush handles can be composted and in normal commercial compost
