The speckle-accented mountain peak tumbler is a fantastic-looking tumbler you should have ready on your desk. This BPA-free tumbler has an outer and inner made of stainless steel and sports a double-walled construction that keeps your favorite drinks insulated whether it is cold or hot. Make sure your drinks are secured as it sports a snap-on spill-resistant lid with rubber gasket that you can drink from through its thumb-sliding cover. With its vacuum insulation technology, you can fill this FDA-approved tumbler with up to 18 oz. of liquid and keep it cool or hot for up to 6 hours. Worry less about it sliding off of your desk as it has a non-slip bottom. Wash it after every use by hand washing only.
