A very cool limited edition toothbrush, for a very cool cause.

I've been a huge fan of the quip electric toothbrush since I first bought it two years ago, and not just because it's sleek and pretty (hello, rose gold). I love the 30-second brushing reminders, and the fact that I get a new brush head in the mail every 3 months without fail. If you've been eying one of these yourself, or you just need an upgrade in the oral health department, now's the time to snag one. They're offering a very cool limited edition gold quip toothbrush that actually gives back to charity. But only for a very limited time.

This special gold quip toothbrush is part of a collaboration with charity: water, an organization which works tirelessly to help end the water crisis in our world. With every purchase of this limited edition toothbrush kit, quip will donate $8.15. Why that amount? Well, it has to do with a little elementary schooler in Washington, DC who lost her two front teeth. The tooth fairy left her $8.15 — and she generously donated it charity: water to help end the water crisis. Now quip and charity: water are trying to show her that her $8.15 really does matter. You'll need to order soon, as they're only offering this promotion in honor of World Oral Health Day (3/20) and World Water Week (which ends 3/22). If there's anytime to get a cool gadget you'll use every day (or preferably at least twice), this is it.
