The Reflo Smart Cup is a 6oz (177ml) open training cup for toddlers, made from unbreakable, high-impact Zylar plastic. It features a patented flow-control insert that allows drinking from any rim point, mimicking real drinking and reducing spills. Its splash-resistant design supports safe, natural oral development without suction or valves, making it perfect for children transitioning from bottles or sippy cups. The transparent design helps kids see how much liquid remains, promoting safety and independence. Easy to clean, dishwasher safe (top rack only), and made in the USA, this cup is trusted by parents and pediatricians alike for safe, durable, and development-friendly drinking training.
