These best-friend necklaces come in nine treat-themed designs, including ice cream-and-cake, coffee-and-donut and milk-and-cookie. "Best friend necklaces have always been one half heart for one friend and another half heart for the other. Now, both friends get to have two charms each so the necklaces are the same but opposite, with one large charm and one small," Violet Gumdrop's Darcee Matlen told TDmonthly.
