Stay plenty hydrated with our Mega 40 oz Tumblers! Made of double-walled stainless steel, these tumblers will keep your drink cold (or hot) for up to 12 hours! Collect them all in our bright and colorful finishes like this one in our bright floral garden print! We designed them to have a large handle so you can easily carry this mega tumbler anywhere and the 3-inch wide base fits most car cup holders so you can bring it along for a quick drive into town to road trips! It comes with a reusable straw and tight-sealing lid with two positions so you have the option to use the straw opening OR close that straw opening with the built-in seal and uncover the wide mouth opening. These tumblers also make great gifts for friends, family, teachers, helpers - anyone!
