This is a small product with a big impact. Each time you purchase one of their environmentally-friendly bamboo-handled toothbrushes, Smile Squared donates one to a child in need. These soft bristled brushes are fair trade, BPA free, and they come in biodegradable packaging. Rethink Buying: turn a ho-hum, everyday purchase into a vote for the environment and give a kid a reason to smile. Available in adult and child sizes.
