The TUM TUM Tippy Up Sippy Cup has a nifty weighted straw that follows the liquid as the cup is tipped up, so that the user is never sucking at fresh air. Nor does it contain any sort of valve, meaning that the little one doesn’t have to suck hard to release the liquid. A simple flip-top lid bends the straw over when not in use (e.g. for carrying around in a bag), keeping the straw hygienically clean but also preventing any of the drink from escaping. -Tippy up cup available in various designs (series 3) - Weighted straw technology – drink any way up! - Handy measure on the side - Flip top leakproof lid - Dishwasher safe - BPA & Phthalate-free - Spare straw and brush set available - Suitable for age 6 months +
