The needles have a small ball at one end and are tapered to a point at the opposite end. I make needles to order. If you want one with a round ball or oval ball, please let me know. They are not made to insert. One tonifies points by touching the rounded end of the teishin to the meridian point. Cover the oval end with the index finger. When the Ki is felt to be present, quickly withdraw the tip of the teishin keeping the meridian point covered with the finger. This jump starts the ki along the meridian. Most acupunturists I know use the ball on the meridian point. I've heard of one practitioner, very macho fellow, who uses the pointed end on the meridian point. I guess you could call that 'yang style'.

Highly polished. Hand made with love. Ki not included!
