Two-needle, four-thread overlock sewing machine MO-1000M. - Model Name: MO-1000M - Brand: JUKI - Number of Spools: 4 - Function: Overlock - Color: White This is a two-needle, four-thread overlock machine! What is overlock? Regardless of the stretch of the fabric, it's the process of simultaneously performing edge stitching and main stitching when sewing two layers of fabric together. It's not just convenient because it can be done in one step! It's also because when using highly stretchable materials (jersey, leotards, etc.) the more sewing steps there are, the more the material stretches, which can reduce the quality of the finished product! ☆ Usage Frequency Purchased in September 2022, used about 5 or 6 times. It's in beautiful condition with no scratches. An essential feature for an overlock machine: ● Easy and convenient automatic threader! Accessories Controller, net, spool caps, presser foot, looper threader Head cover → No stains, some wrinkles. Waste fabric box, instruction manual, instruction DVD The outer box has been discarded, so I will pack it carefully and ship it. Thank you!
