•NO METALLIC TASTE, PURE COFFEE FLAVOR – Looking for a coffee mug that doesn't taste like metal? KOYASU Ti-Zero is built from Grade 1 pure titanium (TA1), a chemically inert and flavor-neutral metal that adds no detectable metallic aftertaste to your drink. Unlike stainless steel tumblers, your coffee tastes like coffee, your tea tastes like tea, and your water tastes pure — sip after sip, even for the most sensitive palates. BPA-free and non-toxic.
•LEAK-RESISTANT FLIP-TOP LID WITH REMOVABLE STRAW – Designed to prevent spills during normal upright carry in car cup holders, backpack side pockets, and tote bags. The dual-mode lid lets you sip directly via the flip-top, or use the included reusable straw — easy to detach for thorough cleaning, or swap with your own. Both modes fully gasketed for everyday commute use. Best stored upright in bags for optimal seal performance.
•KEEPS HOT 6 HOURS / COLD 12 HOURS – Wondering how long it stays hot? Double-wall vacuum insulation between two pure-titanium walls keeps coffee piping hot for up to 6 hours and ice-cold drinks chilled for up to 12 hours (tested at sealed lid, 95°C fill, 25°C ambient). No sweating exterior, no burning your hands. Whether you need hot coffee for the morning commute or cold water for an all-day hike, Ti-Zero holds the temperature.
•16.9 OZ CAPACITY, 150G MUG BODY – Holds a generous 16.9 oz (500ml) of coffee, tea, or water. The mug body weighs 150g (5.3 oz); total weight with leak-resistant lid attached is 230g (8.1 oz) — 42% lighter than a comparable stainless steel travel mug body. A comfortable carry weight for all-day use. Slim 2.8-inch base fits standard car cup holders; 7.6-inch height slides into backpack side pockets.
•PURE TITANIUM INSIDE AND OUT – NO STAINLESS STEEL – Why does titanium matter? Stainless steel tumblers contain nickel, chromium, and manganese that can leach into acidic drinks like coffee. Ti-Zero is whole-body Grade 1 pure titanium (TA1) — the same medical-grade material used in surgical implants and dental devices. No coating to peel, no paint to chip, no heavy metals to worry about. Just polished titanium with naturally formed crystal facets.
•BIOCOMPATIBLE TITANIUM — LOW-REACTIVITY HYDRATION – Pure titanium is the same biocompatible material trusted in surgical implants and dental devices — chosen for its non-reactive, chemically inert nature. Unlike stainless steel which contains nickel, chromium, and manganese, Ti-Zero is ideal for users with metal sensitivities or nickel allergies. Free from BPA, BPS, phthalates, and chemical coatings — a clean choice for everyday hydration.
•PREMIUM GIFT BOX WITH SURPRISE PENGUIN – Searching for the perfect gift for a coffee lover? Ti-Zero arrives in a premium black gift box with the tumbler, leak-resistant flip-top lid, removable reusable straw, straw cleaning brush, AND our signature handmade "Chief Warranty Officer" penguin — a tiny crocheted mascot guarding your Lifetime Warranty. A thoughtful, ready-to-gift set for birthdays, Father's Day, Mother's Day, housewarmings, weddings, and corporate gifting.
•WIDE MOUTH DESIGN — EASY TO CLEAN – Tired of scrubbing narrow water bottles? The wide-mouth seamless interior fits ice cubes, frothy lattes, smoothies, and standard ice trays — and cleans effortlessly without bottle brushes. Top-rack dishwasher safe; hand wash recommended to preserve vacuum seal integrity. (Not for microwave or open-flame use due to vacuum-insulated construction.)
•LUNAR CRYSTAL FINISH — LIGHT-CATCHING TITANIUM SURFACE – Lunar's signature look comes from naturally formed titanium crystals — multi-faceted polished surface that catches light from every angle, with subtle shifts of silver, blue, and violet as you turn it. Each piece is one-of-a-kind because the crystal pattern forms naturally during finishing, never identical twice. Bonus: the faceted surface is naturally fingerprint-resistant. Built for office, commute, travel, gym, and weekend coffee runs.
•KOYASU LIFETIME WARRANTY – BUILT FOR THE LONG RUN – Stand behind every cup, for life. Register your Ti-Zero at koyasu.shop within 60 days to activate Lifetime Warranty coverage on the titanium body against manufacturing defects. Questions or claims? Our Chief Warranty Officer (yes, the penguin) is on duty. From your first morning brew through years of weekend adventures, KOYASU is built to be your everyday titanium mug.
