Forget flossin' — it's a lot more environmentally friendly to use your money to brush. All corny jokes aside, though, these cute new Source toothbrushes ($6.95) are a pretty cool idea. Their heads are replaceable, and the handles are made from responsibly sourced recycled materials — the most entertaining of which is dollar bills. It's not exactly something you'd bring out on the cocktail party circuit, but it would save you from consigning a lot of toothbrush plastic to the landfill. Plus, you'd get to brush like a baller. Would you consider buying a toothbrush like this, or do the handles not appeal?
