Impress your friends at a party, please your partner at a meeting or simply enjoy a refreshing drink by the pool. NATURAL AND SAFE - The box contains 9 reusable luxury cooling stones made from highly polished FDA black granite. This implies that this product is perfectly suitable for direct contact with food and drink. THE PERFECT GIFT - Whiskey Stones includes an elegant wooden box and velvet pouch, making it the perfect gift for those who want to enjoy their drinks to the fullest.
