Item description according to supplier: To avoid problems with your sewing machine, use a BOHIN needle! Our needles are made of nickel-plated steel, which allows them to glide perfectly through the fabric. Their manufacturing process is designed to achieve an optimal balance between strength and flexibility. The flat heel guarantees a precise fit of the needle. In order to achieve perfect curls, each heel is adapted to the needle diameter, which results in the optimal distance between needle and claw. The needles are numbered from 60 to 120 which corresponds to their diameter. Measured in 100ths of a millimeter. A 60 needle is 60/100 of a millimeter. The important thing to remember: the higher the number, the better suited the needle is for thicker fabrics. Our needles can be used on all major brands of machines.
