Thermos Kids Stainless Steel Funtainer Water Bottle with Straw, Dishwasher Safe, Leak Proof, Dinosaur, 14 oz

I plan to buy more of these as these are our favorite bottles for school or to take on outings. they are easy to assemble, easy to clean, they are very spill proof, and definitely easy to drink from. The only time these ever leak is if the straw part gets dislodged from the bottle ring at the top. there's like a rubberized piece that fits into the bottle's ring and sometimes my daughter will accidentally push it downward into the bottle itself and it'll leak but that's very rare. If you fill it to the top with ice the ice will keep for about a day.

Bought for my 4 year old granddaughter and it’s perfect. I love that she can take a juice filled thermos anywhere around the house and I really don’t have to worry at all about spills! And it’s THE ONLY way she’s allowed to drink in my car! The design is so cute, the screw on top makes it secure, the closing cap keeps the straw clean (great for outside), and the straw top comes apart for easy cleaning.
