Core Concepts and Key Technologies

Double-Wall Vacuum Insulation

The double-wall vacuum insulation is the primary technology ensuring that beverages maintain their desired temperature for hours.

Inner Wall: Crafted from food-grade stainless steel, providing corrosion resistance and flavor neutrality.

Outer Wall: Remains cool to the touch and provides structural integrity.

Vacuum Layer: Eliminates conduction and convection, minimizing heat transfer.

Hammered Exterior: Enhances grip, visual appeal, and durability.

Thermal Performance:

Hot beverages: Up to 2–3 hours

Cold beverages: Up to 4–6 hours

The rounded rim also contributes to thermal comfort, allowing users to sip safely without direct contact with excessively hot metal edges.

Rounded Rim Design

The rounded rim is a key ergonomic feature:

Comfortable Drinking: Smooth curvature enhances user experience, especially during prolonged use.

Safety: Reduces the risk of lips injury compared to sharp-edged tumblers.

Aesthetic Appeal: Complements the hammered exterior to create a balanced, premium appearance.

This design makes the tumbler suitable for high-end bars, corporate settings, and outdoor events where presentation and usability are equally important.
