A new flavor of one of America's best-selling candies has just hit Japanese convenience stores. You can now pop white, light pink and dark pink raspberry-flavored M&M's (¥100) into your mouth. The candies are cute, but might be a bit too sweet and artificial-tasting for those who prefer something subtler. Unlike other candies that come and go, these raspberry M&M's will be around for a while — Mars Japan says that it will keep them on shelves for at least a year.
