Choose Colors That Match Your Life Style! Stay hydrated all day with this large 40 oz tumbler that fits just about any car cup holder. Take it with you wherever you go!

Greatyos tumblers are insulated with a double-wall vacuum, built from kitchen-grade 18/8 stainless steel. This double-walled vacuum technology can keep your drinks hot for 8+ hours or cold for 24+ hours. Keeps cold drinks cold and hot drinks hot until the last sip.

The tumblers feature twist-off lids and silicone gaskets to create a leak-proof seal, so no more sticky messes. The flexible, ergonomic comfort-grip handle provides a comfortable carrying experience, allowing you to easily transport your ice-cold drinks to work, meetings, the gym, or trips out of town.

Cleaning your tumbler couldn't be easier, just pop them into the dishwasher. Spend less time hunched over the sink and more time doing the things you love. Greatyos is here to make it easy!

Unlike normal cups, these double-wall insulated tumblers are over-engineered for durability. Solid engineering means they can take a beating. Everything is made with BPA-free material, so your drink stays safe to consume. Greatyos tumblers come with a limited lifetime warranty against manufacturing defects. Rest easy knowing we've got your back through it all.

Whether you're indoors or outdoors, take it to the gym, work, camping trips, music festivals, or just use it at home. Stay hydrated wherever you go. The new factory building has been fully put into use, and the new production equipment and modern management system ensure the quality of our products, reduce the defective rate, and lower the manufacturing cost. We hope our products will appear in more people's homes and bring some interesting changes to your life!
