Designed to be used for drinking in a semi-reclined position, the Wonder-Flo Cup keeps mealtime less messy! The construction of this cup stops liquid from flowing when the user isn’t drawer, and features a rubber button that releases small amounts of fluid for controlled feeding. This cup is microwavable and features autoclave nylon. This cup includes a lid, and replacement lids are available as well. Excellent for personal use at home or professional use at care facilities.
