BONGEN TUMBLER

"MUSTARD"

This is a high-spec double-layer vacuum tumbler.
With a capacity of 350ml, it is neither too large nor too small and can be used for any occasion.
The color is mustard.

Stress-free drinking comfort

Designed to provide a natural drinking experience similar to that of a glass or mug, the tumbler has no screws or other protrusions, making it easy to drink from anywhere in a 360 degree angle. The structure catches ice and prevents the drink from spurting out, allowing the user to comfortably drink to the end.

Excellent heat and cold retention effects

The bottle body is made of double-layered stainless steel. A vacuum between the outer and inner bottles prevents convection currents from dissipating heat, resulting in a high heat-retaining effect. It keeps the temperature at 65°C or higher and 8°C or lower for 6 hours, allowing you to refresh yourself at any time with a delicious temperature. In addition, the design prevents dust and other particles from entering even when the lid is removed, eliminating the need to open and close the lid every time you drink, thereby preventing any interruption to your work.

Tough, durable materials

In order to ensure long-lasting use of the bottle, we paid careful attention not only to ease of use but also to the materials and texture. The body of the bottle is made of rust-resistant and durable 18-8 stainless steel, and the surface of the colored type is powder-coated to prevent scratching.

Clean Surface Finish

Made of high-quality stainless steel, the bottle allows you to enjoy the original aroma of the drink. The inside of the bottle is electrolytically polished for a smooth surface finish, making it resistant to odors, tea stains, and other stains for clean use.

The best coffee flask, and stylish too

I have had many coffee flasks and this is by far the best one. It holds the coffee securely without leaking, and the top has 2 parts which makes refilling easy and drinking hot coffee safe. Looks stylish too. I love it.
