CAPLAN COOLING TECHNOLOGY - Filled with a technologically advanced cooling gel, Caplan Cooling Technology (CCT), which is designed to freeze faster and stay colder longer than any other wine stick on the market. WINE AERATOR & POURER - Built in Aerator that aerates wine as it is poured through the wine stick. Combined with a unique pourer design, wine is poured with a smooth flow every time. BOTTLE STOPPER - Comes with a bottle stopper that inserts into the end of the wine stick. This preserves your wine, maintains the cool temperature of the wine, and ensures that there are no spills. The stopper is so secure that you can lay the wine bottle flat in the refrigerator and it will not leak! This is something that no other wine stick on the market can say. EASY TO USE - Leave your wine stick in the freezer for at least 30 minutes, then put it in your wine bottle and pour cold wine right through it. When you're finished, just rinse it off and put it back in the freezer for next time. Our product fits into all regular size wine bottles. HIGH QUALITY MATERIALS - Our wine sticks are made from Kitchen Grade stainless steel to ensure the highest quality. They are designed with a strong rubber piece around the neck which allows the wine stick to create a firm air-tight seal in the bottle to ensure no spills. Because we are so confident that our wine stick is the best on the market, we offer a satisfaction guarantee. If you are not absolutely happy with your purchase for any reason, simply send it back for a full refund.
