Core Features
Double-Wall Thermal Insulation
The stainless steel double-wall structure locks in temperature efficiently, keeping hot drinks warm and cold beverages chilled for extended periods. It also prevents exterior condensation, avoiding water stains on surfaces.
Practical & Stylish Cap Design
The original stainless steel screw cap ensures a tight, leak-proof seal, while the embedded bamboo detail adds a touch of natural elegance. The integrated handle allows for comfortable, one-handed carrying—ideal for commutes, hikes, or daily outings.
Stable Cork Base
The natural cork base enhances stability, preventing the flask from slipping on smooth desks, tables, or countertops. It also adds a textured, eco-conscious finish that complements the bamboo and stainless steel materials.
Large-Capacity Convenience
With a 650ml capacity, the flask holds ample beverage for all-day hydration, perfect for work, travel, or outdoor activities without frequent refills.
