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

The 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 and sharp shards to prevent injuries.
