This high-performance nipple pump offers many possibilities of professional nipple stimulation. Since the cylinders are transparent, the intensity of the suction effect can be seen at any time and can be dosed easily. An important point to avoid injury from excessive vacuum.The wide flanged, transparent suction cylinders keep the vacuum constant, regardless of whether it is particularly low or particularly strong. Thanks to 2 separately controllable rotary valves in the hose, the vacuum can be distributed evenly and unevenly to both cylinders. A suction cylinder can also be used alone if required.At the tip of each suction cylinder is a white clamping valve with metal lock. Moreover, the hose can be removed from the suction cylinder with a single finger pressure without the vacuum being lost. Position the cylinder, adjust the suction intensity, disconnect - that's it.The large nipple suction pump can be operated intuitively with one hand and allows very precise metering of the vacuum. For a quick reduction of the suction effect, a quick-release valve at the tip of the pump with a stable push button ensures a quick release. The suction cylinders are dimensioned as pleasantly spacious. Ideal for the stimulation of nipples, but also very well suited for other sensitive body parts.Product details✓ 2 heavy-duty cylinders with precisely adjustable suction effect✓ Suction effect can be dosed from gentle to extreme✓ With 2.5 cm inner diameter ideal for nipples and other body parts✓ 2 stable rotary valves for synchronous and asynchronous suction✓ Removable air hose easily detaches while maintaining suction✓ Large, easy-going one-hand pump✓ Quick air release valve✓ 100% silicone hoseTotal length: approx. 70 cmDiameter of cylinders: approx. 3 cmInner diameter of the suction opening: approx. 2.5 cmMaterial: Acrylic (cylinders), Silicone (hose), ABS (handle, release valve), POM (connector)Color: Black, Red, White
