Zak Designs 4pk 16.5 fl oz Plastic Bluey Straw Tumbler Set: Kids & Toddler Cups, Dishwasher-Safe, Multicolor

The color change factor added that extra WOW to the cups. The lids remind me of the sippy cups I used when I was a kid in the 1990's. The size is a little over a pint which is good for both of the younger and older Bluey fans of the family. The number of cups was a great value, complete with lids and straws of course ;)

Such amazing quality! What a deal for 4 toddler cups!

These are great cups that, if spilled or tipped over, leaks very little. A great thing when you have little ones!

So easy to use! My kids love them!

Kids were graduating from sippy cups to regular cups. I needed a way to entice them. We had gotten some free color changing cups at an event and had loved them so I looked for more and found these. They work great. Yes the color changing works best with ice, but ice is colder so it makes sense. I like that this comes with lids and straws also so my younger kid can use them too as he isn't fully ready for open cup yet. The are easy to wash and have been great for us

Such fun cups for any Bluey fans! I use these as my kids’ smoothie cups and they work great.

Perfect for little ones.

Love these cups and so do the kids

One of the kids broke the first time my kid dropped the cup from counter height

A color-changing Bluey cup is a delightful burst of fun for both kids and adults alike! As you pour in a cold drink, watch in awe as the cup magically transforms from one vibrant hue to another, revealing beloved characters from the Bluey universe. I love how it comes with lids and straws and that my 3 kiddos dont fight over them! these are amazing

These cups are adorable, and my daughter really likes them. The Bluey artwork is well done. Also the colorful lids and straws are a festive touch. They survived their first wash without scratching the paint off of them, and I have a tendancy to overwash, and scrub hard. My only criticism is the color change is not as dramatic as expected. Overall these cups are very nice though.

Normally I would just say they are Bluey and in our house that’s all that is required but they have the special added bonus of changing color when you put cold stuff in them that makes these the kids go to cups at meal time!

I received these products for free from the Hey, Bullseye™ sampling program in exchange for my honest review. Ordered these cups for kiddos aged 6-10 and they were a hit! Although they don’t do much for keeping drinks cold for a prolonged period of time, the kids have so much fun watching the cups change colors. We were also able to incorporate the lesson of how the process happens into our homeschool science curriculum. So it was a win for mom too! The only complaint from the kids was that the kids didn’t all match exactly and there was a duplicate in the straw colors which may or may not be an issue between the kids later. Great cups with a fun design that I definitely recommend!

My Grandbaby loves these cups! She loves when they change colors! The cups are cute and easy to clean. These cups are a must for Bluey fans!

My 3 yo son loves his new Bluey cups. Sometimes I (mom) even use them because they’re so cute and fun to drink out of. Even though it says dishwasher safe, I recommend hand washing them to protect the quality of the cups.

These cups are pretty cute, and they do change color as advertised. You to have to use ice water, which isn't an issue for us as we always use ice in our waters anyway. We really only use them once in a while because they don't keep water cold, so they aren't our favorites. Nevertheless, the kids enjoy them either way. They're something fun and different.

My toddler loved Bluey and my child has been super excited to drink EVERYTHING from this cup set. Super adorable, the characters are all on the cups! The lids fit snug on the cups knocking off one star because its not leak proof that should be required for any child cup. If cup remains less than half full a small child shouldn’t have any spills unless they hold it upside down it will leak from the hole for the straw. Any cold beverage thr cup color darkens super cool placing the whole cup in freezer and watching it return to room temperature. Cute set for boys and girls to share.

I got these because my kids and their friends like Bluey. I thought the color changing would be fun. I didn’t notice any change in color when filling up with water from our fridge. I was pretty disappointed by that. Otherwise they make a great cup for kids.

They’re cute but while they are dishwasher safe, it WILL ruin the color changing ability after a single wash even if you put it top rack. Ask me how I know.

These incredibly cute and color-changing tumblers are decked out in characters from "Bluey." Each cup is perfect for a child's small hands and the mix & match lids and straws make it easy to change up the color scheme. My kids love the color changing element, which makes the cup appear darker when cold liquid is inside. These are great for meal time, or short car rides when you kiddo wants their own to-go cup.
