From Bamboo Switch:
Our all natural and vegan Bamboo Beard Grooming Brush is perfect for any hair type and will give your beard a nice and smooth finish and shape. Being that this is a completely earth friendly and sustainable product, it is entirely compostable at the end of its lifespan.
 
Cleaning: For a simple clean-up, let the brush sit bristles down in a solution of vinegar, tea tree oil and peppermint oil for about 30 minutes.
