The Curvy 2+ is the second model in the Satisfyer Curvy+ Series. The first model in the series features a larger suction nozzle, a slightly thicker ergonomic shape, and internal and external ribbed texture for stimulation and grip. The body is also made of ABS plastic. The Curvy 3+ has a much smaller suction nozzle for very precise circular stimulation and a flatter and wider design. Like the Curvy 2+, it's completely coated in silicone. Otherwise the three models are essentially the same product.
