Nova - Chinese eggs that come in three different sizes and weights. Vaginal training eggs, called Kegel, are also suitable for strengthening the pelvic floor and for stimulation when infiltrating one of the eggs inside the vagina or self-indulging when you want to pamper yourself. A woman first experimenting with Chinese eggs can start from the light egg and to create a stronger internal irritation can be replaced with heavier eggs. All products in the kit are made of hypoallergenic silicone and water resistant.
