Great cup

Love this mug. Great for water. Love the option of using a straw with the lid or taking the straw out and sealing it.


Love it!! Love the design!!!

Muy Caliente!!!

The BEST tumbler I have ever owned!!!! Ice stays frozen until the next day!! I was a big fan of the 32 ounce tumblers but had issues trying to find handles for them as I like my tumblers with a handle. I am so glad I updated to the 40 ounce tumbler WITH THE BUILT - IN HANDLE!! 10000% Happy and you will be too when you purchase yours!!!!


Beautiful design—so pretty and delightful! Perfect to inspire water consumption during the busy holiday season. Want it with me all day! Love it!
