I used it once, but it didn't suit me, so I'm selling it. It might be for kids. I will disassemble, clean, and disinfect it with alcohol before shipping, but please be aware that it is not new. There are no instructions or case. You can find how to use it on YouTube by searching for "dial hair cutter". I have difficulty checking Mercari notifications and replying to inquiries during the day. To avoid trouble, I'm sorry, but I would appreciate it if you could purchase it at the listed price.
