I purchased this new for around 1700 yen, and it has been tested and is confirmed to be working. It has a mosquito repellent mode and an LED light function. The instruction manual is not in Japanese, but the operation is simple and easy to use as follows: 1. Press the button once to turn on the mosquito repellent mode. 2. While the mosquito repellent mode is on, press the button again to turn it off. 3. Double-click the button to turn on the LED. 4. While the LED light is on, double-click the button to turn off the LED. To ensure a smooth transaction, please refrain from purchasing if you have negative reviews. I do not smoke and do not own pets. I ship by the next day after payment is confirmed, using "Rakuraku Mercari便 (Yamato Transport)", which is the safest and fastest shipping method on Mercari, with tracking available. Customers paying at convenience stores/ATMs, please purchase only if you can pay within 1 hour. #Gift #Points #PointConsumption #PointRedemption [2026 Latest Improved Version] Mosquito Killer 360° Ultrasonic Powerful Insect Repellent Pest Control 15㎡ Effective Range 20Hz-100Hz USB Rechargeable 2 LED Lights Outdoor Insect Repellent Mosquito Repellent Mosquito Repellent Measures Portable Odorless Non-toxic Non-radiation Safe Travel/Entrance/Camping/Indoor/Outdoor/Fishing/Park/Sports/
