Purchased in September 2025, the product was opened but never used. Only the instruction manual for the heat ceramic is missing. I believe there are no other missing items for both the heat ceramic and timer. The items are in beautiful condition, so I would be happy if you would consider them. Please check the official website for the size and specifications. This is a set of a heater for small pets and a digital thermostat with temperature control. - Model: Heat Ceramic 100W - Function: Heater for small pets - Model: Digital Thermostat 300 - Function: Temperature control Pet Heater Thank you for viewing.
