They are second-hand ultrasonic sewing machine, after repainting, replacement panel, stell use of the old motor and transformer, and then re-combination. Of course, that low price ultrasonic sewing machine totally can't satisy your need!!! For such cases, the factory solemn promise: Our factory machines are totally new. customized rollers More information would provide as soon as receive your kindly inquiry!
