This item is a junk product. It's a hair dryer that I purchased in August 2023 for 14,800 yen. I used it almost every day after I bought it. Yesterday, I heard a different sound than usual while using it, and then it stopped working. Currently, it doesn't work at all. Because it doesn't work, please consider purchasing it if you can repair it yourself or use it for parts. The instruction manual is included. I disposed of the original box, and I will ship it in the box of the newly purchased IB-P601. Please purchase only if you understand the above.
