The Tenga Soft Tube Cup gives you complete control over the pressure on your shaft. The sensation that you desire, controlled by how tightly or lightly you grip the Cup. Enjoy a varied sensation every time by adjusting your grip when stroking, or discover the sensations of purely gripping, kneading and massaging. The outer surface is made with a softer plastic material to give you more control over the tightening sensation. Soft Tube Cups’ lotion reservoir and 70 gripping nubs create extra stimulation.
