The "Microtex" sewing machine needle with flat shanks is especially suitable for processing super-fine, modern materials such as microfibres, polyester, coated materials or fabrics with a high amount of fibres. Thanks to its sharp, sleek tip, the needle very easily penetrates the fabric – this results in an ideal "straight” stitch that does not harm the fibres. Furthermore, a tidy seam formation with low seam shirring is produced. The "Microtex" sewing machine needles impress due to their premium quality, have excellent workmanship, and fit all conventional sewing machines with their flat shank design. The practical economy pack contains five sewing machine needles in thicknesses 60, 70, and 80.
