Organ Embroidery Ballpoint Titanium 90/14Long Lasting: The titanium coating allows for less friction on your needle, which prevents dulling of the tip and wear on the needle. This means you can use them five times longer than a non coated needle. These needles should be replaced after 25 30 hours of actual sewing or embroidery time. Large Embroidery Eye: The large embroidery eye prevents thread breakage and fraying. Use with 40 weight or heavier embroidery thread. Works well for metallics.
