The Gangan Cup was created to solve the frustrating problem of kids spilling drinks on mattresses, sofas, and other hard-to-clean surfaces. Its innovative spout design delivers three key features—spill-stop, squeeze-proof, and anti-choke—without needing a traditional lid. Liquid only flows when gently sucked and pressed by the lips and teeth. The patented one-way valve prevents backflow and controls water flow, reducing the risk of bacteria and choking. Safe, hygienic, and truly leak-proof!
