BUZIO 40 oz Insulated Tumbler with Handle — 2-in-1 Leakproof Lid, Double-Wall Stainless Steel

BUZIO's 40 oz insulated tumbler is a stainless-steel bottle with an ergonomic handle and two interchangeable leakproof lids for sipping or pouring on the go.

This tall, 40-ounce tumbler combines durable 18/8 (304) stainless steel construction with double-wall vacuum insulation to protect drink temperature for extended periods. Built with a slim base that fits most cup holders and a comfortable grip handle, it includes a 2-in-1 lid system (straw + spout), a premium gift box, and a user manual so you can start using it right away.

How does the BUZIO tumbler keep drinks cold or hot for so long?

Double-wall vacuum insulation reduces heat transfer between the inside and the outside of the bottle, slowing temperature change. The medical-grade 304 stainless-steel body and tight-sealing lids help maintain conditions, and the sweat-resistant textured coating prevents condensation on the exterior.

• Vacuum insulation preserves cold for up to 48 hours and heat for up to 24 hours.
• 18/8 (304) stainless steel resists corrosion and flavor retention.
• Two leakproof lids minimize air exchange and spills when sealed.

What makes the 2-in-1 lid system useful for everyday life?

The interchangeable lids give you the option to sip through a straw or drink from a spout for faster hydration. Both lids are designed to seal completely when closed, and the straw lid includes a protective cover to keep the nozzle clean during transport.

• Straw lid for easy sipping during exercise or driving.
• Spout lid for quick gulps when you’re on a hike or commuting.
• Both lids are BPA-free Tritan plastic and fully leakproof when sealed.

Will this tumbler fit in my car and be easy to carry?

The tumbler’s T-shaped base measures 2.16 inches across, designed specifically to slide into most standard cup holders. The ergonomic handle makes one-handed carrying comfortable and secure, while the slim midsection (3.98 inch diameter) keeps the bottle easy to grip and store.

• Base diameter: 2.16 inches for cup-holder compatibility.
• Body diameter: 3.98 inches; total height: 13.78 inches for tall capacity.
• Curved, non-slip handle molds to your hand and lies compact when stored.

How easy is the tumbler to clean and maintain?

The wide 2.28-inch mouth makes it simple to add ice, pour liquids, and clean the interior by hand or with a brush. The Tritan lids are BPA-free and the stainless-steel body is dishwasher-safe, although hand-washing the lids and straw parts helps preserve seals and finish.

• Wide mouth accepts large ice cubes and simplifies scrubbing.
• Dishwasher-safe stainless steel body; hand wash lids to extend seal life.
• Includes two straws and a straw brush for thorough cleaning.
