Are you not that happy with your breast size? The Fröhle breast pump provides better blood circulation and increases breast sensitivity. The breast pump features a grip pump that provides maximum 800 Mbar (millibar.) The clear, flexible cup has a diameter of 135 mm, a depth of 130 mm and it fits a C-cup. The set comes with two tubes, attachment for the grip pump, pressure regulator, T-Connector and a release valve. With regular use, a visible improvement can be achieved in the long run and breasts feel fuller and larger. Application: First, apply some cream to the breast. Next, position the cylinder over the breast and push it against the body. Connect the vacuum pump\'s tube with the tube connector on the cylinder, and create a vacuum by gently actuating the grip pump. Be aware that the sensitive skin of the breast needs to adjust slowly to the negative pressure. During use, frequently open the pressure regulator. That can allow the circulation to return somewhat. Then pump again
