Re-Play Replacement Valve for Sippy Cups - Easy to Clean, Made from Food Grade Silicone - Set Of 6

So far these are the best leak proof, long lasting sippy cups that I have found. Easy to clean. We have lost several of these plastic pieces, so I love that I am able to purchase additional.

Great for sippy cups, easy to use. Great size and fit,with leaks proof quality. Clear color.

I got these to work with the replay sippy cup bottles. They are the perfect replacement and cost efficient for how many you get. We always ended up loosing one or two valves somehow so this pack is perfect and allows us to make sure we always have spares.They work just like the original ones that come with the comes. If you tighten the cap as it should be, there is no leaking whatsoever.

Leak proof. Fits well. Same durability as original. Easy to clean with bottle brush. Works well for my kid.

Would buy back ups just in case. It gets loose around the mouth piece after a while & it’ll leak. Nice to have back ups on hand.

Best Sippys I've found. Available replacement stoppers are a huge plus. A little pricey, but worth it. No leaks, no drips, just the right size.

Love these they fit perfect in the replacement of the ones i messed up i. The garbage deposal by mistake. Instead of buying new cups, i replace these peices that I messed up and now have a few extra in case of emergency.

Why are they so expensive?!Work to keep their supply chia 75% leak proof. Will stretch out and fall off over time.
