Exquisite Dual-Layer Hand-Carved Craft Details. Every glass undergoes dozens of precise manual cutting & polishing steps. Mixed Dual Pattern Carving. Central symmetrical diamond frames enclose fine starburst asanoha lattice panels on the front and back, while sharp slanted blade facets wrap the cup’s sides to amplify light scattering. Amber Cut-to-Clear Overlay Technology. The smoky amber outer coating is partially chiseled away to expose transparent crystal carving lines, creating soft contrast between dark gradient tint and bright clear faceted details. Short cylindrical shape with balanced grip; thick weighted faceted base prevents tipping over, smooth polished wide rim delivers comfortable sipping experience. Tiny subtle variations exist on each glass’s carving lines, confirming genuine artisanal craftsmanship you cannot get from mass-produced machine glassware. Precise Product Dimensions & Capacity.
