Thank you for viewing. I have disinfected and cleaned it lightly with alcohol wipes, but there are some minor scratches from use and some stickiness remaining due to the aging of the material. Even so, I think there should be no problem with its use. I have also reconfirmed its operation before listing it. There are other sellers who are using multiple settings as a selling point, but in most cases, whether paid or free, it's difficult to use them as is. I have left the settings I personally used, but ultimately, it's best to find the settings that suit you based on a template. There are plenty of free articles online about how to start it up and setting templates, so you should be able to use it without any problems by referring to them.
