Feeding your baby while on the go has never been more convenient than with Flipple, the adapter that allows a nipple to be added to bottled water. The adapter is funnel shaped making adding formula to the small water bottle opening possible. You no longer carry multiple baby bottles when the Flipple adapter is kept in your bag and car meaning that all that leaves the house are clean nipples and water can be bought as need. This guarantees fresh, clean bottles at all times with minimal cleanup. BPA Free and passes all safety tests. Made in the USA. Offer includes 1 Flipple adapter, stage two nipple with collar and cap.
