Bigger really is better!

Calling all mermaids! If your birthstone is a sea shell, then you will adore the iridescent hues of blue and purple in this fantastical finish.

Thanks to our triple insulation technology, this tumbler keeps drinks cold for up to 24 hours and hot up to 3 hours. This larger version of our classic tumbler still features a slim profile, making it cup holder friendly and comfy to hold. The increased capacity means you get to enjoy more of your favorite drinks with fewer refills!
