Purchased for around 5,000 yen in August 2024 and used a few times at work, then stored at home. As shown in the second photo, the back has a zipper, allowing you to take out a USB cable for power. There are three levels of wind strength. The third level makes a bit of noise, but it shouldn't be too noticeable while in operation. *Effective when used in conjunction with air conditioning. Stored in a bag, and used only a few times, so it's practically new. There are also no major scratches or odors (such as sweat or tobacco smell). For those who tend to sweat on their rear, why not give it a try?
