HORIE Saiko Series: Iridescent Titanium with Rainbow Hues

The HORIE Saiko Series is a visual masterpiece where science meets Japanese artistry. These signature titanium tumblers are renowned for their stunning, luminous rainbow colors—an iridescent effect achieved through HORIE’s proprietary process of light reflection on the oxidized surface. No dyes or coatings are used; the vibrant finish is a result of pure titanium craftsmanship, creating a piece of functional art that shifts colors in the light.
