Hegen PCTO™ All-Rounder Crown Blue

Bottles are easy to clean and easy for your baby to use

Really great product. Doesn't leak. Perfect leakproof sippy cup attachment. Would not recommend for hand washing, as it comes apart in 4 pieces (if you are a nut like me and need every part to be clean). Great for transitioning baby/toddler from nipple to drinking out of a cup. Happy with my purchase.

Buying more of these to convert the rest of our bottles to sippy cups. Our son uses these well, and I like not wasting the bottles.
