Vinymo MTB is easy to thread through needles and produces beautiful stitches because it resists fraying and unraveling after sewing. It is hand-wound onto cardboard. The length is not exact, but more than the calculated value is wound. Please understand that this is stored at home and hand-wound by an amateur.
