TYESO Vacuum Insulated Tumbler MUG STAINLESS STEEL 600ML

Description:

This is a sleek, double-walled vacuum-insulated tumbler designed to keep your beverages at their ideal temperature for hours. It comes in a stylish, possibly ombre or gradient finish—appearing to fade from a lighter tone at the top to a darker, grayish color at the bottom. The tumbler has a wide mouth and a secure lid with a dedicated opening for the included reusable, collapsible straw. The design is both functional and aesthetic, featuring the brand's tagline "Make Wonderful Life" and logo on the side. It's an excellent choice for daily use, whether you're commuting, at the office, or enjoying a day out.

Feature: 

The defining feature is its vacuum insulation technology. This structure creates a vacuum layer between two walls of metal, which drastically minimizes heat transfer via conduction and convection.

This means the tumbler can keep hot drinks hot (like coffee or tea) and cold drinks cold (like iced water or smoothies) for a significantly longer time than a standard cup or mug. It's built for all-day temperature performance.

Material:

Stainless Steel

The primary material for the body of the tumbler is almost certainly food-grade stainless steel (often $18/8$ or $304$ grade).

This material is chosen for several important reasons:

Durability: It is highly resistant to dents, scratches, and rust.

Safety: It does not leach harmful chemicals or retain flavors, ensuring your drink always tastes fresh.

Insulation Performance: It is a key component of the double-wall, vacuum-insulated structure necessary for superior temperature control.
