Sidagar Ceramic-Coated Insulated Coffee Mug – Pure Taste, Refined Ritual
Elevate your daily coffee ritual with the Sidagar Lingmu Coffee Mug—a perfect fusion of sophisticated aesthetics and professional-grade functionality. Crafted with an S31603 stainless steel body and a ceramic-coated interior, this 420ml tumbler preserves the authentic aroma and flavor of your coffee without any metallic aftertaste.
✨ Key Features:
Premium Ceramic Coating Interior: Unlike traditional stainless steel, the S31603 ceramic liner resists coffee acid corrosion and prevents flavor transfer—endorsed by baristas for pour-over, cold brew, and latte art.
Long-Lasting Temperature Control: Double-wall vacuum insulation keeps beverages hot for 6 hours (up to 41°C) and cold for 8 hours (as low as 9°C), making it your perfect companion through long meetings or morning commutes.
360° Leak-Proof & Portable: Engineered with a secure screw-on lid and silicone gasket, this mug is completely leak-proof—even when tossed into your bag upside down. The 6.8cm base fits most car cup holders for stress-free driving.
Effortless One-Handed Drinking: The flip-cap design features a smart snap-lock mechanism that won‘t bump your nose while sipping, delivering a smooth, slow-flow drinking experience.
Wide 7.5cm Mouth & Easy Cleaning: The large opening accommodates pour-over drippers, latte art pitchers, and hanging ear drip bags. Every component is fully detachable and washable for thorough, hassle-free cleaning.
Versatile for Any Beverage: From hot coffee and tea to iced juice, yogurt, cola, and milk—this tumbler handles it all without retaining odors or stains.
Premium Exterior Finish: The high-grade lacquer surface is wear-resistant and dirt-repellent, available in three elegant color options: Metallic Latte (calm & sophisticated), Glazed Neon Purple (vibrant & open-minded), and Satin Rose (soft & healing).
