Special 10th anniversary version with new designs. It's hard to believe that ten years have now passed since Tenga Eggs first came into our lives. To celebrate a decade of success for the pioneering adult toy, Tenga has produced this special version: the Tenga Eggs 10th Anniversary Pack. There are six all-new Tenga Eggs included: Egg Wavy II, Egg Boxy, Egg Brush, Egg Tornado, Egg Sphere, and Egg Silky. Each is made with the usual Tenga approach to detail and design, fine-tuned to stimulate and pleasure with every stroke.
