The NUK First Choice Training Bottle helps ensure a problem-free changeover to drinking without your help. The NUK First Choice silicone spout is pleasantly soft and spill-proof. Silicone is a rubbery, elastic-like material that is particularly soft, extremely heat-resistant and neutral in taste. It is free from harmful substances, boil-proof, odourless, transparent and has a smooth surface. It has the NUK Air System which equalises the pressure in the bottle and helps reduce colic as less air is swallowed. 

The handles are ergonomically-shaped and have non-slip soft studs.
