The Boon Modster is a cool sippy cup that grows with your child. Have the pick of the Modster litter and choose between a soft spout for those new to the sippy cup world or a firm spout for the pros. And unlike the potential for a big spill with a regular cup, there's nothing scary about this sippy cup with a leak-resistant spout. Your child can enjoy the beverage of his or her choice in two different colors. Plus, mix and match tops and lids because they're all interchangeable.
