Set of Marukan 40W Heat Lamp and Minimal Thermo Used a little two years ago. The cable has been chewed. It was used after being chewed, but it worked without any problems. Cable has bite marks. Please use after wrapping with vinyl tape, etc. The thermo unit's power cord has only been chewed. We are not responsible for any accidents, fires, or injuries after use. Please use at your own risk. Please use it only when someone is watching. We don't know how much the light bulb has been used, so it may burn out quickly. We have not confirmed the operation recently. No box or instruction manual for the thermo unit.
