Having never used a Tenga Egg before I though I'd try this one, it is surprisingly good. The clusters of nubs provide a lot of stimulation. These eggs are described as single use items but mine has no visible wear yet, and has been used multiple times. The white rubbery material seems like it could last a few months if used carefully, just wash it after each use. It comes with a small packet of lotion. Overall very pleased with this item.
