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. Because the box is thick, 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 is here! For mask-related stuffiness & hands-free use] To prevent pollen and virus droplets, wearing a mask is necessary in daily life, 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 unique design with a high-performance double turbine & high-volume, quiet fan, and the upward-facing fan cools the neck, face, and back of the neck in a three-dimensional way. By efficiently cooling the neck, it also cools down the body temperature, reducing mask stuffiness and preventing heatstroke in the hot season! Also, unlike handheld portable fans, this neck fan is a new type that you wear around your neck like headphones, allowing for hands-free use, freeing you from the hassle of holding it. It's great for various situations such as camping, sports, running, travel, outdoor activities, commuting, and going to school. [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 like 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 intake port is efficiently guided to the air outlet, ensuring absolute reliability and making it feel 10°C cooler than the outside temperature. Furthermore, with our 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 back of the head.
