Cute Tumblers

Got these for the Derpy picture and am happy so far. Sturdy handle and build for hopefully many uses.

Huntrix Lovers

I was surprised at the quality of these cups, especially at the price for not one but TWO cups! My Huntrix lover was so excited to see these in our grocery haul when I came home. Easy to clean also!

Great for school!

My kids were excited to see these characters on Zak! tumblers. We’ve used this brand since they started using no leak cups and these are just as good as long as the straw is closed. Wished they had more variations in the packs or ways to mix and match without having to buy all the packs. (I.e. Huntrix/Saja Boys, Derpy/Saja, Derpy/Huntrix) The cups could have more images/print on them. There’s enough blank spots for the kids to decorate with stickers though!

I'm sad that the picture of the black one is different from what is actually on the ones I received. The advertised image is way cuter

your child will take the top off to drink.

Love the color and fun design. But to drink out of the water bottle is a disappointment. Having to open the top and fix the straw over and over. Kid is taking the top off to drink because they are unable to make a full contact with the top and straw.
