Marukan Thermo Thermostat Purchased February 2025, used only during winter. * The triangle mark for setting the temperature was difficult to see, so it has been marked with a black marker. * The included ring was loose from the time of purchase, so a larger ring has been attached. * There are no other stains or issues besides the triangle mark being written on with a marker, but to avoid any problems, the condition of the product is listed as "No noticeable scratches or stains." * Please refrain from purchasing if you are not comfortable with used items.
