If you love java but worry about staining your pearly-white teeth, two brothers in the U.K. made the first colorless coffee in the world.

After suffering from the major downside of all-day coffee drinking, David Nagy and his brother Adam started a business called CLR CFF that makes transparent coffee from "high quality Arabica coffee beans and pure water." 

"We are heavy coffee drinkers," Nagy told The Evening Standard. "Like many other people we struggled with the teeth stains caused by it. There was nothing on the market that would suit our needs so we decided to create our own recipe."

Clear Coffee does not contain preservatives, artificial flavors, stabilizers, sugar, or any other sweeteners, making it only a four-calorie drink. Nagy added, "Because of the hectic lifestyle we lead we wanted to make a refreshing ready-to-drink coffee which provides the boost but is low in calories."

A two-pack costs £5.99, which is about $7.50 for two 200-milliliter bottles. For more information, check out their official website here.
