CLINQ'S copper wine pearls keep your wine chilled without watering it down like an ice cube would. Each pearl features a glycerine core within a stainless steel body and food-safe copper pvd finish. Simply place them in the freezer for a couple of hours and they're ready! These reusable ice cubes come with a copper pair of tongs for each drink placement and a velvet pouch for safekeeping. The copper wine pearls set is presented in a gift-style box.
