Features

Sturdy and Durable Material

This 11 oz stainless steel coffee tumbler is expertly crafted from high-quality 304 stainless steel. Renowned for its exceptional corrosion resistance, it can effortlessly withstand the corrosive effects of various beverages. Even after prolonged use, it remains free from rust and deformation. Boasting remarkable sturdiness, it can endure the impacts of daily collisions and accidental drops without sustaining significant damage.

Waterproof and Leak-proof Design

The tumbler's lid is fitted with a tightly sealed silicone ring that adheres snugly to the rim of the cup. This design ensures that there is no leakage, even when the tumbler is turned upside down or vigorously shaken. As a result, it can be safely placed in a backpack or a car cup holder without any concerns about spills.

High-strength pressure resistance

Stainless steel has high strength. This coffee cup can withstand about 500 Newtons of pressure without obvious deformation and damage, and can cope with daily squeezing.

High-precision Manufacturing Process

Employing advanced CNC (Computer Numerical Control) processing technology during production, we ensure meticulous precision. The thickness error of the tumbler body is strictly controlled within ±0.1 mm, and the clearance between the lid and the cup mouth is accurately maintained at 0.2 mm. This high level of precision contributes to the tumbler's superior quality.
