The NUK sesame street transition bundle is the perfect transition from bottle feeding to independent drinking. Both the active and learner cups feature a soft spout that is gentle on teeth & gums. The learner cup has easy-to-hold handles that can be removed as baby ages, and the active cup has a convenient carrying clip for on-the-go use. Both cups are ultra-lightweight and 100% leak-proof, spill-proof. Plus, the transition bundles includes a 2-pack of Size 2 pacifiers, now featuring NUK's new and improved orthodontic nipple. Pacifiers come in a reusable storage case that allows for easy pacifier cleaning. Just fill the case to the indicated mark, place pacifiers inside, and microwave for 4 minutes to clean the pacifiers. All items in the Sesame Street transition bundle are BPA-Free and Dishwasher safe.
