Seirin needles are composed of three parts: the needle shaft, the handle, and the guide tube. Since the structural design is very simple, the needles must be perfectly uniform and of superior quality. What makes this realizable is our top-of-the-line manufacturing technology. At Seirin we use an automated and integrated production system that combines our advanced technology with original production techniques, enabling us to produce safe and reliable needles that are trusted by acupuncturists and other such practitioners, and patients.
