This is a panel heater suitable for reptiles, amphibians, insects, and other similar uses. I am selling it because I no longer need it. Size: 16cm x 16cm Power and heat generation have been confirmed. It is not a new item, so there may be some scratches and dirt. Please refrain from purchasing if you are overly concerned about the condition. Please check the photos for the condition and only proceed with the transaction if you understand the condition.
