Made of safety glass (tempered glass). Glass that has undergone thermal treatment for toughening, which improves its mechanical strength, thermal resistance, and safe breakage properties.

Tempered glass is 5 times stronger than regular glass, maintains its characteristics at low and high temperatures, and withstands temperature fluctuations.

In the event of breakage, it shatters into relatively small, harmless pieces instead of large, sharp ones to avoid injuries.
