Boon Snug Silicone Sippy Cup Lids and Straws - Includes 3 Lids and 3 Straws - Convert Any Kids Cups or Toddler Cups into Straw Sippy Cups - Toddler Feeding Supplies and Travel Essentials - Green

As a grandmother I have a dozen sippy cups that take up so much space in my kitchen and only get used once or twice a week. These were a great find. I bought a set of 8 oz. plastic glasses that nest to use them with, and now I have so much more space. I bought a second set for my daughter to use when she has the kids on the road to their other grandma's house. When you unfold the inner side of the top it is easy to stretch it over the top of the glass, and they stay in place. They clean up in the dishwasher easily.

These are just what we need. It's impossible for us to keep track of all the matching cups, lids and straws. Having these has made so many small daily frustrations just go away. They stretch quite a bit, I have one over a small section of a stacking snack trio right now. As for all the comments that point out that this can be a nice water toy once a toddler learns to press down, the remedy is extremely easy. Some people snip the vent a bit to prevent it. But I've found it's easier to just put the straw into the slit for the vent, leaving the straw opening free for air pressure. Yes, this makes it so it'll leak of your kiddo throws it. But it's a normal strsw... It can leak anyway if they do it right. Nothing is going to be completely perfect but this is close enough for us! It's been pretty easy to teach my 2 year old that when she spills she will clean up with me, and if she spills on purpose she loses three from to hold her cup. I think the age range for this item is a pretty decent age to also stay learning such rules. We will definitely buy again. I can finally throw away the 10 random lids that don't fit any of the 20+cups we have, and throw out most of those cups without stressing out about finding lids for them

This is perfect for a baby/toddler who is ready (thinks they’re ready) for a cup, and for parents who know better. The lids are smaller, even though they’re stretchy, and will only fit on a kids size or plastic cup. The straws are also short (not not so short that i worry about my baby swallowing or chocking on it), which is great, but is another reason you will want to use on a shallow and small cup, as the straw will not reach far) They have the potential to be way more hygenic than the plastic baby cups with lids that have a rubber nozzle/nipple, bc you dont need to take the cup apart to wash. And admittedly, there have been more than a cup-ple (heehee) times that i have had to either scrub or throw away our baby cups due to forgetting to separate the rubber nipple part from the plastic lid while washing which has resulted in build up underneath where the rubber meets the plastic. This solution has solved that issue for me. It also performs as promised being nearly leak proof (i give 5 stars here anyway bc kids are very inventinve and will still find a way, but the mess is minimal to none). The grip is very strong and tight around the cup. No way my baby can get it off. It can be a struggle to put the lid on a very full cup for this reason. You have to reaaaallly stretch and pull, but for good reason. Also, it’s a simple solution to throw in the diaper bag to have available at a restaurant etc without having to pack a cup that i just know is gonna leak all over the place (you know this happens to you too, despite how tight you twisted that sucker on) The one thing i would love to see, that could be adapted on the straw or included as a separate piece, would be a mechanism to keep the straw in the cup and in place, like how some of the childrens’ toothbrushes have a ring around it to prevent it from gagging or chocking them. This would eliminate one of the leak/spill possibilities by making it harder to expose the hole where the straw fits in as well as aid our toddlers who are still learning in keeping the straw in the liquid instead of pulling it up too high and sucking in air (and playing with it) as my baby does. All in all though, i really like this product and only wish it came with more. I will likely buy again

Not the greatest. "Snug" really wouldn't be the word that I use to describe these. It was a nice thought to convert any cup into a straw cup, but these lids do leak. If you're thinking of giving a toddler any cup with this lid on it, the liquid inside and the lid create an annoying vacuum that actually lets the liquid out. It is very annoying and I don't even use them.

We started out with Boon Nursh bottles & they have lived up to every standard I hoped for so we I found these lids, I was SOLD! I gave everything 5 stars because it’s awesome! The straw/lid combo is obviously not leak-proof if turned over but the seal around the lid is 100% perfect! It’s so easy to clean, yes it’s silicone so fuzz can stick but a baby wipe fixes it right up! It’s perfect for traveling! I buy the boon storage lids and they travel that way. I use the boon storage containers to hold the silicone lids until I’m ready to use them.. Keeps them clean and organized! The the lid/straw combo: the lids are silicone. The straw is hard plastic. You can see them used on the 4 ounce bottle and the 8 ounce bottle. The 4 ounce is easier to hold for my little one. The 8 ounce would be perfect for a toddler. I take the nipple out of the ring on the bottle, screw the ring back on and then put the silicone lid on. It’s hard to stretch and out on but that’s what gives it it’s seal. For the zippy cup lid: its 100% silicone. I held it upside down and it didn’t leak but if the sucking part is pressed & it’s upside down it will leak. I take the nipple out of the plastic ring and screw the plastic ring back on and then put the silicone sippy lid on. My little one loves to chew on it and has no problem getting drink out (7 months). We mostly use the 4 ounce bottle because it’s easier for her to hold. The silicone drop in still works as normal and collapses as she drinks.

Works great for smoothies and messy toddlers!

Bought these to use on some stainless steel cups for my 1yo. The concept sounds good, they won’t spill, but the result is disastrous. I used them about 2x and never again. You pull the silicone lid tightly over the cup with the straw in it. There’s no air space around the straw so it can’t leak. Ok, but then if you or your kid touches the lid AT ALL while picking up the cup, pushing down on the lid, the cup becomes a water cannon and blasts water up the straw. Terrible design, no idea how this made it through product testing.

Hard to get lid on. Water squirts out even when picking up cup. Tried to return and they said to keep it.

Buena opción para cubrir pero creo que solo funcionan con vasos de boca pequeño. Pensé se expandirían más
