Best By Far
Love that you can close the straw. Perfect for traveling and throwing in a bag filled and not have to worry about spilling. Fits cup holders better that others while still being 40oz. Great color selection.

Love this new Era Flip!!! I want so many more, and LOVE that you can have a straw and hide it from dust and germs!! Only thing is, when you slide it too fast, the straw flings water everywhere!

Best mug ever!
I had been looking into another mug to use while working & decided to purchase the 40oz Era Flip top. It keeps my water cold & doesn’t spill if I accidentally knock it over on my messy desk. I love this mug!
