Travel Mug Destructive Testing

Yes, we beat this travel mug sample with a hammer. Both sides of the hammer. And we hit very, very hard. This destructive testing is vital because "stainless steel" is a broad term, and the differences in quality are staggering. Cheap alternatives often use lower-grade alloys that skimp on chromium and nickel, leading to eventual rust, metallic tastes in your coffee, and dents that compromise vacuum seals. We are exclusively utilizing high-grade, food-safe 18/8 (304 grade) stainless steel. 304 contains 18% Chromium and 8% Nickel. The scratches you see in the image reveal that even when the brushed surface is breached, the integrity of the metal beneath remains uncompromised and corrosion-resistant. By prioritizing superior metallurgy now, we’re ensuring your Canard travel mug is a durable, long-term investment rather than disposable landfill fodder.
