Super heavy machine. Comes in a metal case that transforms into a work area you attach the machine to. It is operated with your leg instead of a pedal. I can't figure out how to use it. I have found the bag of accessories that comes with it. There are discs, needles, foot pedals and other things. http://silkmothsewing.blogspot.com/2011/09/green-machine-elna-supermatic.html?m=1
