Organ Jeans Needles have a slim ballpoint that is suitable for sewing with jeans, canvas, coated fabrics, artificial leather, or similar thick materials. The slim, sharp tip reduces drag as the needle penetrates the material, preventing needle and thread breakage. For better distinction, the piston is colored blue. Organ Needle Company is the largest industrial needle manufacturer in the world. Many sewing machines are factory shipped with these top-quality needles. Organ Needle's eco-packaging is sold exclusively through Sulky. Favorite Uses: Great for sewing on medium-weight fabrics, heavier cottons, light denims, and for threads from 40 wt. (lighter) rayon and poly - to 30 wt. (heavier) cottons, and regular sewing threads. Needle Point: Slim Ball Point Needle Style: Machine Needle Type: Jeans
