Zak Designs 15oz Disney Frozen II Movie Kelso Travel Straw Tumbler Plastic and Silicone with Leak-Proof Straw Valve for Kids, 2pcs Set, Frozen 2 Olaf

I am actually the person who avoids reusable plastic whenever possible. I would a million times prefer glass. I feel even worse about silicone. I know it's supposed to be safe but it just doesn't seem to me like a good idea or that it may get clean enough, even though I know it probably gets plenty clean because it can be boiled. Mostly, I'm OCD and just worry about nastiness bleeding through/staining. However...I have a toddler, and desperate times call for desperate measures! XD He absolutely cannot have glass bottles. Or glass bottles covered in silicone. Because they still can break, and there's no way that is feasible right now. This is actually the only product I've found where *THE STRAW GENUINELY DOES NOT DRIP. AT ALL. EVEN WHEN UPSIDE-DOWN.* He was very frustrated at first with learning how to bite on the straw to get the liquid out, and he certainly doesn't like that he can't make a mess with it XD ... but Daddy %26 I do! It really is very impressive how well the valve works. I have found these sippies upside-down in my couch before and had this sinking feeling, but they DO NOT LEAK. Like, at all. I don't know how, but even when they are used a lot they STILL work perfectly. Reassembling them is not too bad once you get used to it. They do seem to come apart and get clean a lot more easily than say a traditional sippy cup with just a couple slits in a spout. It's harder for me to imagine that gets very clean.

My grandchildren love toy story. they were very excited to receive the cups. the design is great. if they tip over they don't spill. You would need to hold it upside and shake it in order for the liquid to leak out. Very easy to wash because the pieces come apart. They are also dishwasher safe.

I am a 48 year old Mother with now Grandchildren and these cups are amazing. Easy to clean they do not leak as long as the littles do not chew the straw. I do thing they need to put extra straw tip and I think they might do that now if you order online. They price is not bad I purchase when they are on sale because I always like a deal!

These Zac cups are my go to without a doubt. They do not leak, at all. My 3 yr old drinks out of regular cups perfectly but of course accidents happen from time to time unless you do what I do and only have drinks in these while in the car or bed or anywhere else you don’t want spills!

These little cups are the cutest! I have not had any problems no leaks spills and my baby loves them!

I absolutely love these cups I have not had any problems out of them no leaks no spills and they are so adorable

I would say this is the best choice I've come across for a toddler drink cup. The valve or whatever that keeps the liquid from spilling is awesome. My son still doesn't want these a lot of times because he is still mondo obsessed with his bottle. I've tried several different kinds and no luck so far. I don't like that it's all plastic, personally.....BUT.....I can't offer a better solution. Can you imagine glass?!? Stainless steel would be so heavy and there's some concerns with that, too. So I would say, of what is out there right now, this is my pick. The pattern is rave, of course. ;) HELLO KITTY!!!

Typibal "Bait %26 Switch" scheme : cup is not as illustrated ... listed as TWO cups for $7 - would be shipped separately. But what shipped out was 1 SINGLE little cheapie plastic cup with built-in straw at $13 instead. Ceap little pieve of junk not worth 20 cents DON'T FALL FOR THIS ! ! ! !

I ordered these cups because they were supposed to be spell proof. My grandchildren ages. 4, 3, 2 and 1, when we put the juice and milk in them they promptly tipped them sideways and upside down and dripped and leaked all over. The straw also doesn't stay intact.

We ordered these cups because they said they were no Spill but all four of our kids tipped them upside down and sideways and they started to drip right on out of it. The straw also doesn't want to stay in Its sleeve up at the top of the cup.
