The orthodontic shape of the NUK Trendline dummy ensures a correct bite and the whole jaw line and the colourful design will please your baby. The anatomically shaped mouthpiece fits snugly over your baby's face and has a special vent. Like all NUK dummies Trendline has a valve system NUK AIR SYSTEM - air leaves through a special hole, so the dummy stays soft and retains its shape, which prevents the deformation of the child's mouth.Silicone Silicone is a synthetic material; odourless, tasteless, particularly resistant to temperature and light.
