The TENGA EGGs are small, flexible masturbators designed for comfortable use regardless of size. Each egg has a unique exterior design that reflects its internal structure, offering different sensations. The Tenga Misty II model features internal protrusions for enhanced stimulation. The eggs are easy to use and are single-use products: you open it, add the provided lubricant, and after use, you place the egg back in its casing for disposal.
