Instant purchase is welcome. I used this for about two weeks when the pet birds I keep were chicks. It's in good condition and the operation has been confirmed. It warms up quickly, so it's very convenient and reassuring to use. - Model: Flat Heater 6W - Power supply: AC power - Size: Approximately 15cm x 15cm - Target animals: Small animals (hamsters, birds, etc.) - Features: Temperature adjustment function Please refrain from purchasing if you are overly concerned about minor details.
