Ti Zen Pure Titanium Travel Coffee Mug

Key Features

• PURE TITANIUM DAILY COFFEE UPGRADE – KOYASU Ti-Zen Crystal Silver is a 12oz / 380ml pure titanium travel coffee mug designed for clean taste, lightweight carry, leak-proof daily movement, and everyday coffee routines. Built as a premium insulated coffee tumbler for coffee, tea, commute, office, car, and travel.
• PURE TITANIUM BODY, NATURALLY STABLE SURFACE – Made with a pure titanium body, KOYASU Ti-Zen uses a premium metal valued for biocompatibility, corrosion resistance, lightweight strength, and natural surface stability. A stronger material story than ordinary stainless steel drinkware.
• NO METALLIC ION LEACHING, NO METALLIC TASTE – The titanium drinking surface is flavor-neutral and corrosion-resistant, helping prevent metallic ion leaching into your drink while reducing unwanted metallic taste transfer. Your coffee tastes like coffee, your tea tastes like tea.
• NO COATING, NO PAINT, NO LINING – Crystal Silver showcases the natural character of titanium itself. There is no interior coating, no synthetic paint layer, and no lining between your drink and the titanium surface, creating a true titanium coffee travel cup experience.
• LEAK-PROOF THREADED SCREW-SEAL LID – KOYASU Ti-Zen uses a threaded screw-seal lid with a silicone seal to help prevent leaks during commute, office, car, backpack, and daily travel use. Tighten the lid fully and keep the seal properly seated for best leak-proof performance with coffee, tea, iced coffee, and cold drinks on the go.
• LIGHTWEIGHT 12OZ / 380ML DAILY SIZE – Designed as a compact coffee travel mug for home, commute, office, car, and short trips. The titanium body weighs approximately 150g, making it easy to carry while still giving you a premium metal coffee tumbler feel.
• DOUBLE-WALL INSULATED FOR DAILY DRINKS – The vacuum-insulated structure helps maintain drink temperature during normal daily use. Ideal for hot coffee, tea, iced coffee, and cold drinks. Expected performance: hot up to 3 hours and cold up to 12 hours depending on use conditions.
• WIDE-MOUTH EASY CLEAN DESIGN – The wide-mouth opening makes filling and rinsing simple for daily coffee, tea, ice, or cold drinks. The titanium body, lid, and seal are dishwasher safe; for best long-term appearance, hand washing is recommended to help preserve the exterior KOYASU logo.
• CRYSTAL SILVER TITANIUM FINISH – The Crystal Silver finish gives this titanium coffee mug a clean, refined, and minimal metallic look without relying on paint. It fits naturally into home kitchens, office desks, car interiors, cafés, and modern travel setups.
• KOYASU LIFETIME BODY WARRANTY – KOYASU stands behind the titanium cup body with lifetime support against manufacturing defects. Crystal Silver represents KOYASU’s core idea: pure titanium, no coating, no paint, no lining, clean taste, lightweight strength, and a premium coffee experience beyond ordinary stainless steel tumblers.
