Large Eye Titanium Needles (STPD)
These needles combine the larger eye with a titanium coating. The result is a needle that is easy to thread and works great with embroidery threads, yet lasts 3 to 5 times longer than a standard chrome needle. Needle systems include HAx1, 15x1, 130/705 or 130R with a designation of STPD. The ST indicates that the needle is a large eye and the PD indicates the needle has a titanium coating.
