Prym Sewing Machine Needles No. 70-100 Jersey and Leather, in a pack of 10 units, reference 154101 S, is a set of needles with a rounded tip, suitable for jersey and synthetic leather fabrics. Prym is a German brand founded in 1530 in Aachen, the oldest family-owned industrial company in Germany, now based in Stolberg and recognized worldwide for needles, pins, buttons and sewing accessories. The rounded tip keeps the threads away from the fabric instead of piercing them, preventing elastic fabrics like jersey or materials like leather from tearing during sewing. It is a preferred option for those who regularly sew with these materials that are more sensitive to sharp-pointed needles.
