The Cooling Pearl Necklace is the elegant way to stay cool any time. Whether it’s a hot summer day or you’re just feeling overheated, it helps keep you cool and comfortable. And, the classic pearl look never goes out of style. Each lightweight “pearl” is about the size of a quarter, and is filled with non-toxic cooling gel. Simply place the necklace in the freezer for 4 hours. Depending on your environment, your pearls will stay cool on you for up to 30 minutes of cooling relief. Features a magnetic clasp for ease of use.
