Celebrate a loved one's birthday with a toast and this fun charm in their drink. This slice of birthday cake silicone charm fits inside a Charmers drinking glass or stemless contour glass (both feature a post in the bottom of the glass to hold the charm front and center). And with a unique charm displayed, it's easy to identify your drink among all the other glasses on the table. This pink and blue birthday cake charm makes a great gift for a birthday guy or gal when paired with a coordinating glass (not included).
