Overlock Machine Attachment Rubylock II R-L21 - Model: Rubylock II R-L21 - Accessories: Instruction manual, various attachments - Type: Sewing machine attachment - Made in Japan The Rubylock II is an overlock sewing attachment for use with home sewing machines. It transforms your sewing machine into a 4-thread serger, allowing you to neatly trim fabric edges while creating strong and beautiful professional-quality overlock stitches. Main Features * Product Name: Rubylock II (Rubylock II) * Model Number: R-L21 * Application: Attachment for overlock (serging) with home sewing machines * Manufacturer: Brand of Toyo Seiki Kogyo Co., Ltd. (related company of Toyota Sewing Machine) * Function: Trims fabric edges with a cutter in front of the needle and sews them together by intertwining two serger threads and the sewing machine thread. * Compatibility: Compatible with most home sewing machines (especially low-shank), but cannot be used with special sewing machines that do not allow presser foot replacement. * Advantages: More affordable and compact storage compared to purchasing a separate serger machine. This attachment allows for an overlock finish with the same seam appearance on both sides, like ready-made clothing. Purchased online several years ago, Used only 2 or 3 times and stored. There are no major scratches, but There are marks of the accessories on the back due to poor storage. The color shows signs of aging overall. The included attachments are more than those listed in the instruction manual, possibly due to additional purchase. I think it can still be used. * All items in image ① are included. The instruction manual is also enlarged and uploaded, so please check the images. Since it is a used item, there are some scratches and stains, but I would like to sell it to someone who understands. Please ask any questions if anything is unclear in the images. Please purchase after you are satisfied.
