My kids are obsessed with their Zack cups! Not only are they leak proof but they also keep drinks cold for hours!!! Super easy to clean & grab when you’re on the go! 10/10

I love these cups! They are sturdy, metal inside so easy to clean even a lost cup with lord knows what foul smelling stuff in it, they don’t spill. I absolutely recommend them. I may or may not have even used one for my night stand cause it keeps water cold lol

My girls (2 and 4 yrs old) love love love them so much! The designs are adorable and they’re easy to use and wash. They take them everywhere! My four year old’s hands are big enough to hold one and my 2 year old likes to take it by the straw (maybe not the most sanitary but I love her can-do-it-myself attitude!) My older one picked the clear one because she likes to see how much water she’s filling up and drinking. My younger likes the familiarity of the metallic one as she has the same of a different design. The twin pack also came with an extra mouthpiece and straw. Overall, they have exceeded my expectations and Zak is our trusted, go-to brand for kids’ drinkware.
