The handle is rigid compared to the flexible copper spiral handle. Excellent for classic body acupuncture, ear acupuncture and hand acupuncture. In addition, these needles are heat-resistant and conductive and are therefore ideal for the hot needle technique (with moxibustion) and electrostimulation. The acupuncture needles type KJ have a twisted steel reversible handle and are made of high-quality, stainless, surgical steel. The needle thickness is visible thanks to the colored plastic handle. The acupuncture needles are individually packed in sterile packaging.
