The instruction brochure covers straight and top-stitched seams as well as 3 and 4 thread serged seams, and the techniques you use for each kind. The six blades, two blade holders, and detailed instructions all come in a fitted metal case to keep everything together.
The blades are durable, but replacement blade packs are available for heavy-duty users. Suitable for anyone who does sewing, even on a casual basis.
Made in Canada.
