Come and see our amazing products. Electronic wine stopper has a built-in intelligent electronic sensing system. Insert it into the bottle mouth, and then press the silicone stopper into the bottle, which will immediately trigger the sensor switch and turn on the automatic ventilation function. After the completion of air extraction, the bottle is always in a vacuum state, which has a good storage and preservation effect. When the tilt of the bottle reaches 45 degrees, the anti-pour function will be triggered. Pls confirm with us about the packing info, stock color and exact production time before placing your order.
