These are not typical "home" or "domestic" machines; they are "commercial" and "industrial strength" workhorses designed for continuous operation in professional settings. Longsew offers various types: "straight stitch," "zig zag," "walking foot," "cylinder arm," "double needle," and even "computerized" or "embroidery" machines built to "heavy duty" specifications. They provide machines "for sale" at competitive "prices" for every need, from a "basic" model to an "extra heavy duty" powerhouse.
