Craftsmanship takes rock glass to the ultimate level

The design is simple and comfortable to hold in the hand. It is made by a process called "mold-blowing," in which glass is blown into a mold using a blowpipe. The necessary weight of the seed for each glass is precisely wound onto the blow neck, and experienced craftsmen achieve a "heavy glass pool at the bottom of the glass" while making the mouth part of the drinking cup thin.

The price varies depending on the finish and color.

Frosted glass softly reflects the color.
Frosting a transparent glass gives it a soft frosted glass-like impression. The frosted finish gives the glass a soft frosted look, softly reflecting the color of the beverage poured into it.

Black matte, the ultimate black color that does not allow light to penetrate.
The glass has a unique texture with a low luster that fits comfortably in the hand and is unmatched by existing glasses.
