The Tivax SewSimple Handheld 2-Thread Sewing Machine may be small, but it has a 2-thread lockstitch just like a full-size machine, preventing stitches from unraveling. The machine uses 4 AA batteries or a power cord and is ideal for craft projects and mending. It's also portable and convenient for sewing while traveling. Mend a torn pocket or shorten trousers all within minutes. You can sew projects in school, at the office, or at home.Details:White9.2" x 2" x 4"2-thread lockstitchPowered by 4 AA batteries or power cord (batteries sold separately)
