Everyone has a Stanley or Simple Modern tumbler these days – make yours stand out (and stop people from accidentally taking it) with these cute personalized charms! This set comes with two complete charms: each includes a delicate hand-strung pearl chain and a stainless steel letter of your choice (probably selected during ordering). The chain has a lobster clasp that easily hooks onto the handle of your 20oz, 30oz, or 40oz tumbler. The letters are well-made and the pearl chain gives it a pretty, feminine touch (they also have gold and silver chain options mentioned). They're not just for cups though – you could attach them to a keychain, purse zipper, or backpack for a monogrammed look. Makes a fantastic and thoughtful gift for birthdays, Christmas, Mother's Day, or Galentine's Day. It's an inexpensive way to add a personal touch to a popular item. Note: The tumbler itself is NOT included, just the two charm sets. A simple, effective way to mark your drink in style at the office, gym, or on a trip.
