Sealing & Leakproof Performance
Developed for the global outdoor travel and business trip market, this mug targets core pain points of leakage, impact damage and inconvenient storage on the road. The lid contains a food-grade sealing gasket around its full circumference. Once tightened, it forms a fully enclosed seal that prevents leakage even when the mug is inverted or shaken vigorously, so users can place it directly inside a backpack without risk of spilled drinks soaking clothing, electronics or documents.
Impact Resistance & Structural Build
The mug body adopts a thickened stainless steel structure that resists deformation from accidental drops and impacts, and holds up to rough handling in outdoor settings and uneven hiking routes. The interior uses 304 food-grade stainless steel, paired with a MARSCOAT easy-clean coating that simplifies removal of tea and coffee stains during travel, even without full washing facilities.
Portability & Storage Compatibility
A lightweight thin-wall design keeps overall weight low, so the mug adds minimal burden when packed in a backpack or suitcase. Its diameter is calibrated to fit most backpack side pockets, car cup holders and outdoor gear storage slots for easy access. Available capacities include 280ml, 380ml and 480ml, all paired with a screw-on direct-drink lid.
Customization & Production Details
Dongke Electric Heating supports full-chain OEM and ODM customization for color, branding, capacity and lid structure. Production follows standardized quality control procedures, with 100% in-line inspection of vacuum level, sealing performance and cosmetic defects, plus AQL sampling on finished units. Export cartons include internal cushioning to reduce bump damage during long-distance shipping.
