The Peekaboo straw cups have the perfect size for little hands to hold. Wally pops out of the fun cup splashing waterdrops onto the straw. A practical lid will help keep drinks inside and the straw in place, making it easier for the small kids to use. The cute Wally training cups are made of food grade silicone, making them shatterproof and adds easy-grip features. Dishwasher safe and suitable for use in the oven, microwave and freezer. A practical brush is included for easy cleaning of the straws.
