This product includes a hand-operated pump, a soft silicone Y-connector tubing kit, two breast cups, and a carry case. The pump is manually operated, and the tubing is made from silicone. The breast cups are designed with smooth, rounded edges for user comfort and durability during use. The system is used by placing a cup over the breast area and applying gentle pressure with the hand pump. This creates a vacuum effect that temporarily increases blood flow to the area while the device is in use. The product is intended for short, regular personal care sessions when used according to instructions. The system is available in Small, Medium, Large, and Extra Large cup sizes. Please select the preferred size when ordering. If desired, the system can also be used with a single cup to work on each breast individually. This product is intended for personal use only. Individual experiences may vary. Always follow the provided instructions and discontinue use if discomfort occurs.
