Two tumblers in one

I was really surprised by this tumbler. It fits nicely in my car cup holder. It stays cold, ice not melting over night. Im really impressed with the floral pattern. Its very elegant and the gold trim adds style. I love that it comes with the two sizes of straws. Im so impressed with thr fact thats theres no seal around the top. One less thing to clean and it doesn't leak. Its very easy to open and close. The two lids makes it so versatile. I couldn't ask for anything better.

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.

Two caps included for spout or straw options.

These 30 ounce vacuum insulated cups are perfect for cold beverages and they don't sweat when they're sitting on your desk. I like that it has two lid options: you can use the flip up spout in conditions where you may have a spill, but the straw attachment makes it even easier and more satisfying to drink out of at your desk. Since we wash the lids more often than the entire cup, the second lid also gives you the option of using the cup while the other lid is being washed. Clean up is a breeze with the detachable internal straws (and also the silicone straw attachment which pops out of the lid easily for washing. The instructions say they are top rack dishwasher safe, but we have not tried that yet. These cups are quite large, but they do have a tapered bottom so they'll fit in your cupholder.

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.
