It was suggested to me when I bought my high end machine to keep the box just in case I ever needed to ship it off. I was really happy that I had done that when a yr later I traded it in for a newer model. The person buying it got thier new machine all boxed up like new. I went thru the book and made sure every bobbin, attachment, etc was in there. I have a 400 Kenmore and that box has been long gone. My new Viking Diamond Deluxe is being stored in the shed.
