Weight Approx. 23g (including string part) Transparent red glass is used for the back side of the glass and the loop part through which the string is passed. This is the only glass pendant made by hand by melting heat-resistant glass at a temperature exceeding 2000 degrees with an oxygen burner that is a mixture of oxygen and gas. The heat-resistant glass used as the material is harder and more transparent than ordinary glass, and is characterized by its antioxidant properties, which are resistant to discoloration and deterioration, and are lightweight. This glass is mainly used in the fields of physics and chemistry and optics. The pendant string will be delivered in the same condition as the work image. (It is a brown color wax cord of Mitsuyori string) You can also change the color of the navy or black string. In that case, please let us know at the time of purchase. Since the string has an adjuster, you can slide the adjuster to adjust the length of the string. The work images and videos were taken outdoors in a sunny environment. There may be a difference in the appearance such as color due to the influence of the displayed device. Since it is made by hand, the shape is a perfect circle or sphere, the pattern is symmetric, and it is not the center.
