Mettler Bobbin Fill Thread, white 1000m

For very fine and delicate fabrics and pucker free seams, as well as for high quality serging. Especially good as a bobbin thread in combination with Mettler PolySheen or Amann Isacord 40wt. Core spun construction makes Bobbin Fil very tear resistant and very suitable for commercial and embroidery machines. Provides consistent thread tension for optimum interlacing of the upper and bobbin threads.
