The fine ribs of the Tenga 3D Zen are designed for a more subtle sensation. It has smooth pleasurable strokes with just a hint of tantalising texture to stimulate your senses. It is gentler than some of the other Tenga 3D models and great for those who are extra sensitive. 

It is also good if you're just looking for a slow, lingering sort of pleasure instead of an intense quickie. The Zen is meant to be used slowly, building pleasure up as you leisurely explore the delicate sensations of this premium quality masturbation sleeve. Made of body-safe anti-bacterial Elastomer, the Tenga 3D Zen is safe for sensitive skin and easy to clean.
