Bogobrush

The buy one, give one movement is going strong with companies like Toms and Warby Parker — now Bogobrush ($40) has entered the mix. They offer a fairly-straightforward concept: a subscription service delivering a simply-made, environmentally- and socially-conscious toothbrush every three months (and for every one you get, an American in need gets one as well). The toothbrushes feature an entirely-biodegradable design, thanks to their bamboo construction. This helps you avoid contributing to the 450 million toothbrushes thrown away annually in the USA, all while helping spread good dental hygiene.
