Zak Designs Disney Mickey Mouse Kelso Tumbler Set, Leak-Proof Screw-On Lid with Straw, Bundle for Kids Includes Plastic and Stainless Steel Cups with Bonus Sipper (3pc Set, Non-BPA) 15 fl oz.

Fantastic product ! Leak free ! Perfect design for any Mickey lover withstands the dishwasher!

This was very easy for 4 year old to drink water and milk without the hassle of washing more complicated straw cups!

Great product my son is in the rough stage where everything gets tossed around and they hold up very well. The caps worm very well with the solid straw top replacements. With this we got 1 plastic and one metal cup.

We love Zak Designs cups, and the stainless steel ones are a game-changer—no sweating, no lukewarm drinks, and no sad, melted ice. That said, these things are heavy. My toddler has dropped one on his toes before, and let’s just say… lesson learned. Leak-proof? Pretty much. Sometimes a rogue drop sneaks out from the straw slit, but considering I’m not getting full cups of liquid dumped on me anymore, I’ll take it. Bonus: they survive toddler abuse like a champ. Dishwasher safe, which is a must. Only real gripe? The rubbery strip around the lid is not toddler-proof—mine has peeled it off every single cup. It looks goofy without it, but hey, the cup still works. Overall, solid choice for parents who want durability with minimal spills—just watch those little feet!

This cup comes with both stainless and plastic options, and I purchased it to transition my baby from a sippy cup to a straw. While my baby is comfortable using straw cups for water, he refused to do so with milk, and the doctor recommended it to regulate milk intake. I've tried various types, but cleaning and drying the straw proved challenging. I chose this cup based on reviews mentioning its leakproof design. Given that my baby tends to throw things, I started with the plastic version. Once he gets accustomed to it, I plan to switch to the stainless steel cup. I bought this cup a month ago, and just recently, my baby started drinking milk from it accidentally during an outing when I didn't have the sippy cup. After initially refusing for about an hour, he eventually accepted it. I appreciate the cup's quality construction and the flexibility it offers with two material choices. The cute design appeals to my baby, and the straw is robust enough for teething, leaving no marks even when bitten. Overall, a well-made and versatile cup that caters to different situations.
