I purchased this on Mercari and used it a few times. I am selling it because my living situation has changed and I no longer have time to use it. The following information is from when I purchased it: EP-14BB Purchased in April 2019, operation confirmed Instruction manual included I think I used it for about 2-3 months after purchasing it. The silicone mask has been washed, but there are some stains from lotion, so it shows some signs of use. Please purchase only if you understand this. #YA-MAN #YA−MAN
