I love a great partnership, which is just one of the reasons I'm a fan of the new 2012 Limited Edition Designer Series Collection from Tweezerman. The company teamed up with fashion designer Cynthia Rowley to add sporty and graphic prints to its award-winning Slant Tweezer, Mini Slant Tweezer, and Filemate Nail File. The award-winning tools are now as fashionable as they are functional. What beauty partnerships have caught your eye, either for better or for worse?
