Stainless Steel Vacuum Insulated Thermos Cup

A stemless, double-wall stainless steel tumbler that keeps your drink at temperature, from morning coffee to an evening glass of wine.

This is the rounded egg shape people reach for when they want an insulated cup that still feels good in the hand. The double-wall vacuum body slows how fast heat moves in or out, so a hot coffee stays warm and an iced tea stays cold longer than it would in an ordinary cup. The maker states it holds temperature for up to 6 hours.

The inner layer that touches your drink is 304 stainless steel and the outer shell is 201 stainless steel, wrapped in a sprayed color finish. It holds 12oz, about 355ml, which suits a coffee, a tea, water through the day, or wine at dinner. A clear press-on lid sits on top with a small opening to sip from, and it lifts off for washing and refilling.

Key Benefits

• Double-wall vacuum body Two walls of stainless steel with a vacuum between them slow the flow of heat, so hot drinks stay warm and cold drinks stay cool.
• 304 stainless steel interior The layer that meets your drink is 304 stainless steel, easy to rinse and with no inner lining to flake or chip.
• 12oz stemless shape The rounded belly holds about 355ml and sits low and steady on a desk, a table, or a car cup holder.
• Clear press-on lid A see through lid presses on with a small sip opening to slow splashes, and lifts off for easy cleaning.
• Fourteen color finishes Solid tones, soft gradients, glossy rose gold, and printed finishes, so you can pick one that is easy to spot as yours.

Best for: coffee and tea at your desk, water on the move, and wine or cocktails at home. One finish, the natural color version, ships without a lid.

How It Works

The cup is built from two walls of stainless steel with the air drawn out of the gap between them. Because heat struggles to cross that vacuum, the drink inside holds its temperature for longer and the outside of the cup stays closer to room temperature. This is the physical design of the cup at work, and the maker states up to 6 hours of temperature retention.

The clear lid presses onto the rim and has a small opening you drink through. It helps slow splashes while you carry the cup from room to room, though it is a press-on lid rather than a sealed, leakproof cap, so keep the cup upright.

How It Fits Your Day

In the morning it holds a coffee or tea while you get going, and it still feels warm when you come back to it. Through the day it works as a water cup at the desk or in the car. In the evening the stemless shape makes it an easy tumbler for wine or a chilled drink, and the sprayed finish gives your hand something to hold instead of a cold steel wall.

FAQ

How long does it keep drinks hot or cold? The maker states up to 6 hours of temperature retention. Real results depend on the starting temperature, how full the cup is, and how often you open the lid.

Is it leakproof for a bag? No. The clear lid presses on and has an open sip hole, so it slows splashes but is not a sealed, spill proof cap. Carry it upright rather than loose in a bag.

What is it made of? The inner layer that holds your drink is 304 stainless steel, the outer shell is 201 stainless steel, and the lid is PP plastic. The outside wears a sprayed color finish.

Does every color come with a lid? Most do. The natural color version is listed without a lid, while the other finishes include the clear press-on lid.
