Description
The Blue Rola Key Edo Kiriko Whiskey Glass is a bold statement piece that combines vivid color, traditional Japanese-inspired cutwork, and a refined crystal presence.
Its design features a rich cobalt blue upper body contrasted by clear hand-cut crystal sections, creating a sharp rhythm of light, depth, and brilliance. At the center, an elegant starburst motif draws the eye, while the surrounding vertical cuts and fine geometric textures enhance the glass’s sculptural look. The result is a tumbler that feels both powerful and precise—perfect for collectors, whiskey lovers, and customers seeking distinctive luxury barware.
With a 9.8 fl oz capacity, this glass works beautifully for whiskey, bourbon, cocktails, or spirits served neat or over ice. Its larger size and substantial weight give it a premium in-hand feel, making it equally suitable for everyday ritual, entertaining, or gifting.
Each piece is individually hand-cut, so slight variations may appear from one glass to another. These subtle differences are part of the beauty of handcrafted crystal glass and make every piece unique.
The Craft, in Four Steps
Design Drafting
Each pattern is drawn by hand, mapping how light will travel through every facet.
Initial Cutting
Diamond wheels carve the primary facets. One wrong angle and the piece is lost.
Fine Adjustment
Each facet is refined by hand. Depth, edge, angle - adjusted until geometry becomes art.
Final Polishing
Progressive abrasives bring out optical clarity. Light passes through without distortion.
Why Optical-Grade Crystal?
Our crystal isn't just "glass." It's optical-grade borosilicate - the same material used in telescope lenses and camera prisms, chosen for its extraordinary clarity and precision.
When we set out to make the perfect whiskey glass, we didn't start with tradition. We started with a question: What if the same crystal that helps us see the stars could hold the amber glow of your favorite whiskey?
The result is a glass with >92% light transmission - higher than traditional lead crystal - and a hardness that allows for incredibly precise hand-cut facets. It's lighter than lead crystal, yet more durable and chemically stable.
This isn't a cheaper alternative to crystal. It's a better one.
