As the leader of the tweezing tool pack, cult brand Tweezerman has teamed up with fashion designer Cynthia Rowley for a limited edition, four-piece nail tool set. It's the brand's fourth collaboration, and we love the colourful designs. "It was fun to put my own fresh twist on a cult classic product," Rowley told WWD. "A beauty tool should be beautiful." Amen!
