If you have always been looking for the perfect all-metal needle we have got it. Made of Japanese stainless steel, ground to diamond sharpness, hardened several times and coated with an ultrafine layer of medical silicone, this needle type achieves the traditional nearly painless insertion characteristics of the SEIRIN needles. A delicate 25-mm metal handle (most needles only have 20-mm handles) ensures optimal handling. The needle shaft is located precisely at the center of the handle. All of these features ensure superior needle insertion and stimulation properties. You can mix your shopping carts with Seirin L-type (metal handle with guide tube)and Seirin LE-type (metal handle without guide tube)to qualify to our multi-buy discount scheme. It Saves to Buy More with Harmony Medical! Please note that the ME and LE type needles are exactly the same, the only difference being the designation.
