GreenPaxx Universal cup lid fits many glasses and cups 2 Pack Blue

Updated: With the addition of a third ring, these lids do fit a lot of different cups. It fits a 3.5" glass very securely, which is the most common tumbler size cup. As long as it and the part of the glass it touches are dry, it sticks on very well. It's not "spill proof" since liquid can seep from the straw opening. However, it won't spill very much.I love that I can use our regular glasses with our toddler, and I don't have to constantly hover over him to make sure he doesn't spill. He's knocked over completely full glasses twice now, and the spills were very minor. The cap held tight even with the force of a full glass. Moreover, he's knocked over quarter-full glasses a dozen times with no spilling at all. The cap is simple to clean and easy to use. I use it at least three times a day, every day. I'm very grateful to have found these and to be free of those plastic sippy cups.In a humorous incident, my toddler got upset and intentionally knocked his cup over. He glared at the un-spilled cup. Determined to spill the milk, he turned the cup upside-down and shook it. Milk squirted out of the straw hole as he shook it, but the lid held fast. Thanks to the lid, I had a much smaller mess to clean up.There's a trick to help them fit small glasses. Normally, you put the rim of the glass between and inner and outer ring on the lid. For glasses that are a little too small, you can put the rim of the glass inside the inner ring of the lid - the outer ring will hang out over the rim.After using these every day for a year and taking them with us on trips, we still think they're fantastic.

I bought this lid to use with a stainless steel Klean Kanteen insulated pint cup. It fits nicely, is secure and very easy to use. I highly recommend these lids for cold drinks. (My problem with the Klean Kanteen lid is it leaks terribly with the slightest tip.)I drink hot drinks from the KK cup and use a glass straw because, while fine for cold drinks, silicone tastes bad in hot drinks (although, admittedly, I have not tried the GreenPaxx straws.) The GreenPaxx lid keeps the liquid from spilling but the glass straw clanks around in the cup with this GreenPaxx lid so it's not perfect but it's better than spilling hot tea every time I get in or out of the car. ... Well, life is full of trade offs and summer's coming, so maybe I'll just have to switch to cold drinks. Thanks GreenPaxx for this brilliant idea!Addition to previous review: I added one star because I ended up trying the GreenPaxx straws and they don't taste bad like the other silicone products I've tried. I still like my glass straw so I just insert it through the green "stem" portion instead of the one that comes with the straw set. Problem solved. Also, I'd like to mention that Jane from GreenPaxx is super with customer service!! Thanks, Jane!

I am not sure why these are titles "spill proof." The caps are NOT at all spill proof. Tested: If you tip the cup on the side it will spill through the hole in the center even with the "patent pending" straws in place. So seems like false or at least rather misleading advertising in that regard. For now I will still stick with an "it's ok" rating since they still have some value in that they fit a fair number of cups and do provide some spill protection in that they will certainly slow a spill down compared to an open container but it would not be long before at least half a cup of juice would be everywhere. The funny part is if you bought a three ring silicone pet food lid and make two cuts crosswise in the center you would have basically made one of these but they are almost about the same price so that is just kind of a funny observation :) Although now I think about if you cut a slighter smaller than exact acrylic straw size hole in the center of one of those lids it would be even more spill proof than these. Hmmmmm......

I was previously using the take-and-toss cups with lids and straws. While it's nice that I don't have to worry about loosing one, they wear out quickly and need to be replaced. The Cool Cap works well with several cups I already had in my house. My favorite is the Green Eats tumbler. This does not fit on smaller juice glasses or regular mouth mason jars. It is not completely spill proof however. My baby can easily get the lid off but my big kids like them and I know it will help minimize spills for them. It does leak around the straw opening too. Amazon is sold out of the Green Paxx straws so I got the pure straws instead. (I am thinking maybe they are a little too narrow for the opening?) Anyway, I am pleased with the purchase despite these minor flaws. I am sure these will last us quite awhile.

I have included a photo of the bottom of this lid. I purchased this lid for when I want to carry a drink with me in my car similar to the style that fast food restaurants provide at the drive up window. I also ordered the "Silicone Reusable Drinking Straws" by GreenPaxx. In my same purchase I also bought "Zak Designs Hammered High Ball Glasses". These lids fit those cups really well.If you like to use a straw with your drink these work as advertised if you have a cup/glass with the correct size as shown in the description "FROM APPX 2.75" to 3.75" RIM DIAMETER" Do not try to use this lids on a plastic cup that will squeeze easily. You want a rigid glass/plastic. These lids fit the wide mouth Ball mason jars (won't work with standard small mouth mason jars).When I put a drink in a glass with these tops, I don't have to worry about the drink splashing all over my car while driving. The description for these lids clearly says "spill resistant". It is expected that turning the drink over will result in spillage just like when you turn over a drink cup from the fast food restaurants. The big difference is these lids are dishwasher safe (tested) and they stay on the cup really well. The GreenPaxx silicone straws fit these lids well.EDIT* I have used my lids, straws, and glasses together for several months with numerous dishwasher cycles and everything is holding up well.

Acquistato assieme a cannuccia della stessa marca; utilizzati in combinazione garantiscono stabilità e funzionalità. Morbidi e facilmente lavabili risultano un ottimo prodotto anche per frullati. Consigliatissimo

Kann ich nur empfehlen. Passen auf verschiedene Durchmesser von Gläsern etc.Die Becher, die momentan überall zu kaufen sind, haben Metalldeckel, die nach kurzer Zeit zu rosten beginnen. Wenig appetitlich!Zusammen mit den Silikon Strohhalmen optimal!

Gran producto. Adaptable a varios tamaños, fácil de limpiar y de muy buena calidad. Mucho mejor de lo que esperaba.100% recomendada si se busca tapas de diferentes tamaños

Ces couvercles sont très pratiques car ils s'adaptent sur différents verres ( diamètre) sans problèmes . La matière est écologique. Ils sont très souples. Et quand la paille n'est pas dedans les couvercles est complètement fermé pour ne pas laisser l'air entrer. Je l'utilise toutes les nuit sur un verre d'eau sur ma table de nuit avec la paille , ainsi pas de risque de renverser quand au milieu de la nuit j'ai besoin de boire une gorgée d'eau. Je les conseille vraiment. Il permet aussi de protéger de l'air mes jus et smoothies frais.Voilà plusieurs semaines que je les utilise tous les jours pour mes grands verres de jus vert ou rouge. Et elle ne se colorent pas. Superbe !

I bought these caps for when my six year old grandson comes to visit as he has a tall beaker he likes to use. The cap fits the beaker perfectly and is very easy to fit. The cap has three rings that stretch and grip different sized cups or glasses. You can use ordinary drinking straws but if you use the Cool Straws they make for a better seal. If your cup/glass does get knocked over the caps are not 100% leak proof, a little does escape from the top where the straw goes in. I am very happy with my purchase of these caps. I no longer need to worry about beakers of pop being knocked over. My grandson is happy too and has given the cap and straws a thumbs up.The caps and straws aren't just for use with children. I look forward to using them when sat out in the garden in the summer. They will keep the flies and insects out of my drinks.
