I am selling this item to organize my belongings. I wore it once and have kept it stored at home since then. I have never used the heater, so I don't know if it works, but I have confirmed that it powers on. - Immediate purchase OK - There may be initial scratches, stains, and imperfections. Please refrain from purchasing if you are sensitive to these. - Will be shipped in a cardboard box. - No instruction manual included. Thank you for looking! Thank you.
