Auxiliary Trivet with Overheat Prevention Sensor, Grilling Stand, Black

This is an auxiliary trivet for gas ranges with temperature sensors, designed to prevent the flame from being extinguished by the sensor.
It is made of ceramic and is used by filling the center part with water.

It has been used a few times, but the main unit is in clean condition. The box has some dirt on it. (It's just a cardboard box.)
