Inner Liner Material & Corrosion Resistance
Built for commuter coffee markets in North America, the EU and Japan & South Korea, this mug addresses daily hydration needs of workplace users. The inner liner adopts 316 medical-grade stainless steel, which delivers stronger acid and alkali corrosion resistance than conventional 304 stainless steel. It safely holds coffee, tea, juice, milk and other beverages, releases no metallic aftertaste at high temperatures, and preserves the original flavor and mouthfeel of each drink without cross-contamination between beverage types.

Coating Hygiene & Easy Cleaning

The interior wall is fitted with the self-developed hydrophilic easy-clean coating under the MARSCOAT line. Milk stains, tea residue and sugary drink buildup rinse off quickly under plain running water, with no repeated scrubbing needed. The coating also comes with antibacterial properties that inhibit the growth of common harmful bacteria, preventing persistent odors from forming over long-term use and allowing users to switch drink types without flavor transfer.
Vacuum Insulation & Lid Configuration
The cup body uses tailless double-wall vacuum technology to block heat conduction and convection. At room temperature, it maintains target temperatures for 6 to 12 hours, keeping hot drinks palatable in winter and cold drinks chilled throughout summer. It has a 450ml rated capacity, comes with a straw lid, and supports an optional temperature display function. The straw design enables drinking without tilting the head back, suitable for commuting and office scenarios.
Sourcing & Quality Assurance
Dongke Electric Heating provides end-to-end OEM and ODM services, including body logo printing, custom packaging design and color scheme adjustments. Every unit undergoes 100% in-line inspection for vacuum integrity and sealing performance, followed by AQL standard random sampling on finished goods. Products are packed in export-standard paper cartons designed to withstand long-haul international transport.
