The Singer 5830C does zig zag, a blind hem, buttonhole and some decorative stitches as indicated on the front of the machine.
It takes plastic 66 style bobbins It’s working well and includes the foot petal and one extra bobbin but doesn’t have other accessories. This model also has the removal sewing bed as seen in the pictures. The manual isn’t included and it’s not one that’s free online anywhere but I will do a video on how to make a bobbin, and how to thread the machine properly and how to use the decorative stitches for the buyer. I’ve serviced it and oiled it myself and all is in working order and sews well. If you have any questions, text me @ 602 five zero nine five zero nine nine
