BONGEN TUMBLER【GREEN】

Designed for a natural drinking experience like a glass or mug, it eliminates protrusions such as screws for a smoother feel at the mouth and lets you drink from any angle, 360 degrees around. Its structure catches ice and prevents drinks from pouring out too forcefully, so you can comfortably finish every last sip.

The bottle itself has a double-walled stainless steel structure. By creating a vacuum between the outer and inner walls, it prevents heat loss caused by convection, delivering excellent heat and cold retention. It keeps contents at 65°C or above for heat retention and 8°C or below for cold retention for 6 hours, so you can refresh yourself at a delicious temperature anytime. In addition, even with the lid removed, its design makes it hard for dust and other particles to get inside, so you don’t have to open and close the lid every time you drink, and it won’t interrupt your work.

Designed for long-lasting use, we paid close attention not only to ease of use but also to the materials and texture. The bottle body is made of 18-8 stainless steel, which is highly durable and resistant to rust, and the colored versions feature a powder-coated surface to help prevent scratches.

Made from high-quality stainless steel, it lets you enjoy the natural aroma of your drinks. The inside of the bottle is electro-polished for a smooth finish, making it less likely for odors, tea stains, and other grime to stick, so you can keep it clean and use it with peace of mind.
