Boon Snug Silicone Sippy Cup Lids - Convert Any Kids Cups or Toddler Cups into Soft Spout Sippy Cups - Toddler Feeding Supplies and Travel Essentials - Pink - 3 Count

These have been the best leak proof sippy cup lids! They stretch to fit most cups for little ones hands. My granddaughter had no problem figuring out how to use them. And we love the pink colors we got! These function so well, we haven’t bought any other sippy cups since using these. Also love that nothing stains these, as she loves carrot juice, which stained other sippy cups we had. (For reference my granddaughter was 10 months old when we started using them, and have been using them for 5 months now). I bought the Wee Sprout bamboo cups for kids, which is the orange cup in the photo, and that’s usually all we use, but I put the lid on a bigger plastic cup to show they fit most cups that we’ve tried, and they don’t leak.

I would give 10 stars if I could. I tell every person with kids to get these. Goes over ANY cup. Not 100% spill proof but since the alternative is a completely dumped cup, this is 99.99% spill proof (a drop or two). Perfect for travel. Dishwasher top rack safe and easy to clean.

They don't leak and stay on the cup.

I love this product for my baby to add to glass or plastic cups if we are out. It is a convenient sippy cup lid. Just note that putting it on certain plastic cups made the cups break and it has to be a certain cup width.

These are great.. BUT they rip really easily. 2/3 have tears in them from the sides of the glass jar that I use it on. Very disappointing, because it happened quickly after buying and it caused them to leak. However, I do like how they fit many different sizes and the concept of them. Just wish they were better quality!

These are great for my 2 year old who still spills. He want to use glasses, so we stick these on them and he is happy. I'll probably bring one or two on our big trip next year.

I cannot for some reason keep up with the little plastic insides of a sippy cup lid. Sometimes they somehow lose the whole lid . These fir almost any cup. I havent had a leak from any of mine. I just grab a cup and pop one of these lids on. Travels great too.

My toddler's loves these for milk! So easy to clean!
