## Description

Tired of leaky sippy cups?  We created our Cool Cap, universal cup lid, to be used with almost all regular drinking glasses.  When we got our first prototype we realized this could be ridiculously useful for adults too.  And as a company, GreenPaxx is pretty obsessed with health drinks.  So we slapped a Cool Cap on a pint glass and understood just how great it was for kids, adults, and heck, even Grandma loves it.   We got about teaching our little ones that they needed to be aware that they are holding a drink, not like sippy cups that get thrown around.  And guess what?  Our kids learned to hold their drink upright, without worrying if they did happen to tip it over, no huge mess. We really wanted an alternative to plastic cups and reusable tumblers...that didn't have heavy metal taste.  You can stretch our universal cup lid over almost any sized glass, for a snug fit, and a spill resistant drink, without the hormone disrupting chemicals found in plastic.   Make your health shake at home and use our Cool Cap on a tall glass along with one of our patented reusable silicone straws.  (sold separately)   So whether you're into smoothies, shakes, iced coffee, juices, or even just want to keep a glass of water by your bedside without spilling, our Cool Cap is perfect to contain your drink, minimize spills, and keep those bugs out of your drink in the summertime.   We also know sometimes it's impossible to avoid plastic altogether.  Like when you're tailgating.  Or at the beach or pool.  Our Cool Cap fits perfectly on a red solo cup for those times you're without your favorite glass.  Makes a unique gift for anyone who drinks smoothies or shakes.

## Questions & Answers

**Q: Will these fit on the small plastic cups that Ikea sells?**
A: Hey Jennifer, this is Cindy, CEO of GreenPaxx.  The Cool Caps were designed to be used with regular glasses, avoiding some of the chemicals in plastic but they will securely fit any cup with a RIM diameter of 2.75 - 3.75 inches.  The cup just needs to be on a flat surface prior to putting the cap on.  They are made of thick, durable, long lasting silicone, so they fit best on durable steady cups.  I've never seen Ikea's cups, but sometimes a thin plastic cup is not substantial enough to support the cap.  Hope this info helps :-)

**Q: I looked around for the 'rocks' tumblers being used by the kids in the picture. Couldn't find them here on Amazon. Anyone got a link?**
A: Hi! This is Cindy, CEO of GreenPaxx. Sorry for the late reply, I missed this message.  Here you go...  And my kids have been using them for yrs without any chipping whatsoever. :-)http://www.amazon.com/Duralex-Picardie-4-Ounce-Clear-Tumbler/dp/B0017LR21Q/ref=sr_1_1?ie=UTF8&qid=1373659574&sr=8-1&keywords=duralex+picardie+tumblers

**Q: Can you fit regular size straw for milk or water (not smoothie size)?**
A: Yes. It wouldnt fit tightly, so some liquid could still spill out from the straw area. But it will hold the straw upright.

**Q: Could a person with manual dexterity problems be able to apply this to a plastic cup without help?**
A: The plastic cup would have to be one of the stronger ones that are sold everywhere now.  I place the lid in the palm of my hand, plop it on the cup & walk my fingers around the edges to make sure it is sealed.  Hope that helps with your question.

    Ideal for the elderly
  

*by C***E on Reviewed in the United Kingdom on 22 April 2015*

This was bought along with the GreenPax straws for an elderly relative who has difficulty tilting their head back and swallowing. It has proved very successful in use with both mugs of hot drinks and glasses of cold drinks. It is easy to clean in the dishwasher after use. One word of warning, the person who prepares the drinks needs to be quite dexterous, as fitting the lid over some hot mugs can be a bit fiddly until you get the knack for each mug size. I would recommend not filling hot drinks too near to the top of the cup while you are learning the technique, to avoid spillage and possible burns.

### ⭐⭐⭐⭐⭐ 







  
  
    Fantastic product. No more spilled pop when glasses/beakers  get knocked over.
  

*by M***L on Reviewed in the United Kingdom on 26 January 2015*

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.

### ⭐⭐⭐⭐⭐ 







  
  
    Love it.
  

*by I***L on Reviewed in the United Kingdom on 20 January 2016*

I was skeptical, but they work rather well.  We only really use them for our 7 and 3 year old's glass of water on their bed side tables so can't attest to proper toddler use.  But I'm pleased with them and our boys like them. Regular straws work ok.  It will drip from the straw opening but that's expected.  It doesn't drip from the rim of the cup.  Excuse me whilst I get rid of all the other cups cluttering my cupboard. Hurrah!
