The glass comes in a dedicated presentation box. The box size is approximately W95 × D95 × H85mm, and the boxed weight is approximately 160g.

Hanabi Motif Appeal

Hanabi, or Japanese fireworks, are strongly associated with Japanese summer festivals, yukata, night skies, and refreshing cold drinks. For international customers, this glass can evoke the feeling of a Japanese summer evening.

When a cold drink is poured in, the fireworks appear on the glass, creating the feeling of a small Japanese summer festival at the table.

Care Instructions

Before use, the glass should be washed. Dishwashers, metal scrubbers, abrasives, strong rubbing, microwaves, ovens, long exposure to direct sunlight, and long soaking in water or lukewarm water should be avoided. There may be individual differences in color development and transfer placement. Cooling the printed area once before use helps the design appear more clearly.
