Thermochromic Straight Cup “Fireworks” (Color changes with cool)

Main Features

This straight glass is part of the cold-reactive series, combining traditional design with modern temperature-changing technology. It is introduced as a BASE limited and quantity-limited item.

When a cold drink is poured into the glass, colorful fireworks appear. The design changes when the glass reaches 17°C or lower, and it returns to its original look at room temperature, so the transformation can be enjoyed repeatedly.

Size and Capacity

The size is approximately 58mm in diameter × 150mm in height, and the capacity is 285cc.

Box

The glass comes in an individual Thomson box, making it easy to present as a small gift.

Hanabi Motif Appeal

Hanabi, or Japanese fireworks, are strongly associated with Japanese summer festivals, night skies, yukata, and refreshing cold drinks. The product page describes the design as memorable and themed around the light of hope that colors the night sky.

For international customers, the glass can evoke the feeling of a Japanese summer evening. Every time a cold drink is poured in, the fireworks appear, creating a small festival-like surprise 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. Depending on room temperature, the design may already be visible when the item is removed from the box. Cooling the printed area once before use helps the design appear more clearly.
