Zak toddler stainless steel cups

Zack toddler cups are fabulous, they don’t leak and they keep everything cold for a long time.

Perfect for hot summer days

Love that these don’t sweat and the ice stays as ice for hours!

Cute but it leaks a little bit

I have a 3 years old and a 2 years old boys; they both like the cups. They are really cute and work great, but they leak a little bit.

These leak like crazy. Out the side, out the straw. If your kids are like mine, and completely fail to set their cup upright often, then best of luck.

wouldn't recommend

cute and can keep drinks cold quite a while but straw leaks if tipped over and sometimes when moving it while it's upright. Big fan of zak products but let down by these.
