Functional, super cute cup! Perfect for any lady

I love the interchangeable lids and the fact that the cup is stainless steel so it keeps things cold or hot for long periods of time. The two pack is the perfect gift for any lady. I love the bow print, I am keeping it for myself and am gifting the purple one for our Christmas gift exchange.

Great cups! Versatile lids!

Very pretty colors! Very neutral and matte. I love that it came with both a straw lid and a spill proof flip straw lid with a handle. The straw for the regular straw lid is silicone material. The spill proof lid is in fact spill proof. It says not to put carbonated drinks in the cup…I tried it with both lids…you can do it with the regular straw lid, but not the spill proof lid. The carbonation builds up and explodes when you flip the straw. I really like these cups! They're great!

Zak designs 30 oz stainless water bottle

Water. Everybody drinks it now. Isn't it better when it's cold and out of your own cup? Look no further. Other brands are more expensive for the same product. This one comes with two separate lids for each cup. One with an exposed straw. The other with a collapsible hard plastic straw. Keeps drinks cold and ice frozen longer than any traditional cups. It can be used for warm beverages as well. Great buy for the price!

Love love it

Absolutely love these cups! I honestly love them more than my stanley cup. Theyre not as heavy as Stanleys and the handle is silicone instead of hard plastic. The colors are so cute and the bottle is so shiny. My new favorite cup.

Solid bottle

These are the perfect size. I love the two straw option. I mostly use the bottle for on the go, but if I am around the house could see me using the straw. My daughter likes the bow cup and brings it to school.

Missing lids

The package arrived missing two of the lids. I tried contacting Sam's and wasn't responded to. The cups are beautiful and work well, but I was unimpressed with the customer service and the mistake made.
