This hand held micro-current device is amazing. It is extremely easy to use and works well with serums or gels or even water on clean skin. I don’t have the box or the paper instructions but it is very easy to work and instructions easily available online including YouTube how to videos. Also see benefits and instructions in my photos. These devices now go for $750 brand new. I paid $700 a few years ago. It has not been overused at all! Is clean, shiny and in excellent condition. The only reason I am selling it is because I purchased a different device. Its a wonderfully effective device! Make an offer!
