Thank you for viewing! I purchased this on Amazon, but I'm selling it because I'm already using a similar neck fan. This product is currently not available on Amazon. I took it out of the box for the photos. It powers on and blows air. Due to the thickness of the box, I will ship it directly in a Yu-Packet Plus dedicated box. How about it for heatstroke prevention? I will sell it to someone who is looking for one. Thank you very much. [The latest 2024 neck fan debuts! For mask-related stuffiness & hands-free use] To prevent pollen and virus droplets, it is necessary to wear a mask on a daily basis, but wearing a mask in a high-temperature and humid environment increases the risk of heatstroke. A neck fan is an essential item for comfortably spending the summer while wearing a mask. Our neck fan uses a uniquely designed high-performance double turbine & high-volume, quiet fan, and the upward-facing fan cools the neck and face, the back of the neck, etc. three-dimensionally. By efficiently cooling the neck, it also cools down the body temperature of the whole body, reducing mask stuffiness and preventing heatstroke in the hot season! Also, unlike handheld portable fans, this neck fan is a new type that is worn around the neck like headphones, allowing for hands-free use, freeing you from the hassle of holding it. It is very useful in various situations such as camping, sports, running, travel, outdoor activities, commuting to work or school, etc. [Low-noise design & enjoy 360-degree airflow] This neck fan uses a quiet fan & high-quality brushless motor that utilizes know-how to minimize noise, ensuring powerful airflow while minimizing noise. You won't bother others even if you use it in a quiet environment such as a library. In addition, it adopts a circulation fan design based on fluid dynamics principles, and by adjusting the angle and height of the blades, the airflow is optimized, so the air taken in from the air intake is efficiently guided to the air outlet, ensuring absolute reliability and making it feel 10°C cooler than the outside temperature. Furthermore, with its unique technology, the airflow is close to natural wind, and 32 wide air outlets cool the entire 360 degrees, not only the front but also the neck and the back of the head.
