The Bentgo Kids Prints Meal Prep Tray & Cover makes meal prep easier than ever by keeping the snacks and meals in your lunch tray fresh–even when they aren't packed inside the outer shell of your existing leak-proof Bentgo Kids Prints lunch box (sold separately). The lid’s snug design and locking clips fit the tray perfectly and offer a sleeker storage option for the fridge when you pack lunches the night before. Plus, thanks to the convenient transparent view, you can easily see what's packed inside without opening the tray cover. Simply grab the pre-packed tray the next morning, remove the tray cover, and pop the tray inside your child’s Bentgo Kids Prints lunch box. NOTE: Bentgo Kids Prints Meal Prep Tray & Cover can be used as-is to transport dry snacks and meals. However, it is NOT leak-proof. To safely transport foods with liquids, always pack the tray inside the Bentgo Kids Prints lunch box (sold separately).
