Superior Titanium-coated Topstitch #80/12. Guaranteed to last 5-8 times longer than regular needles. Pack of 5 needles. Recommended for piecing and quilting with fine threads. Since these new needles have an ultra thin coating of titanium nitride they will stay sharper longer. Topstitch needles have a larger eye and a deeper groove. Good for piecing, embroidery & applique using finer threads.
