Thermos 12-Ounce Funtainer Bottle, Blue

Q: Can you not store milk in these? Looking for a way to keep my son's soy milk cold without lugging an ice pack.

You can definitely put milk in this thermos, but to keep it ice cold you need a water bottle ice pack (the myColdCup ones on Amazon). These work really well because the ice pack is put *inside* the thermos (rather than a bulky ice pack outside), so it does not need to be nearly so big to have the same cold effect. One ice pack in this 12 oz thermos will keep the milk really ice-cold for more than 8 hrs. He will love it!

Q: is this bottle leakproof?

Yes, is is leakproof. If the top is screwed on correctly (not misthreaded) and the straw is pulled through tight, it will NOT leak. The few times we’ve had it leak is due to user error. Though it will obviously leak (little dribbles) if the top is not closed and the bottle is turned upside down or laid on its side. For reference, we’re probably going to buy this for the third time in two years because it keeps getting lost. It’s leak proof and easy to clean (no mold).

Q: Can this bottle be filled with hot water and keep the water warm for hours?

No. It says that ON THE BOTTLE. It’s not for hot liquids

Q: Can i use it for milk

Yes, this could be used for milk, or any other cod beverage.

The straw inside the bottle is plastic no silicone !

I am disappointed, the straw inside the bottle is plastic, not silicone and for this price I was expecting something more healthy, it’s 😞 so sad. Now I need to buy another bottle just to have silicone straw !!
