The inn-stayer's tritan-made tumbler is a great way to have your favorite drink with you everywhere you go. Each tumbler is made of tritan material that is BPA-free and will not break easily as it is shatter and impact resistant. Plus, it sports an easy-to-carry handle, a silicone-made band, and a smooth rubberized finish which makes it comfortable to take around. You will also be assured that your drinks will stay secured in this FDA-approved tumbler as it sports a self-attached spill-resistant screw-on lid you can easily drink from as it has a sip-through lid. Make sure that your 30 oz. tumbler is clean by hand washing it after every use.
