This is a cube-shaped paperweight made of crystal. With its very basic shape and perfect transparency, it contains the beauty that can be found through 'emptiness'. Its heavy weight provides a sense of stability, and its perfect transparency makes things around it appear interesting.

Crystal is glass containing lead oxide. The higher the content, the greater the specific gravity and the higher the refraction of light, giving it a beautiful appearance when crafted. Additionally, it is important to achieve high purity by minimizing the content of impurities that cause coloring. The crystal used in the museum archive boasts perfect transparency as it is the crystal with the highest transparency and refraction, and you can enjoy the beautiful refraction effect wherever you place it.

When maintaining the product, please do not use chemicals and lightly wipe it with a soft cloth.

Crystal shows its beautiful surface when crafted, due to its glass-like characteristic that contains lead oxide; where the higher the content, the higher its density and refractive index. Moreover, it is important to minimize the impurity content that causes coloring to achieve high purity.

The crystal used in the Museum Archive boasts perfect transparency by using crystal with the highest clarity and refractivity, letting you appreciate the beautiful refraction effect wherever you place it.

It is recommended to avoid exposure to direct sunlight and best to be stored in a shaded place. When maintaining the product, please use a soft cloth to clean it lightly without using any chemicals.
