Bottle & Wipe Warmer is a space saving device that handles two baby-care functions in one compact unit. Bottle & Wipe Warmer heats up gradually and stays constant at about 40°C which is warm enough to be comfortable for your baby but never too hot. METM-618 Baby Bottle and Wipe Warmer works with all common bottle sizes and warms up cold formula or breast milk. Bottle & Wipe Warmer features an expandable bottle holder which can be pulled upward for a full covering of the milk bottle to perform a good milk warming.
