TeWa Non-Coated needles (currently available in select sizes):

• Are great for practitioners who use direct moxa, or have patients with an allergy to silicone.
  
• Are bi-metallic, composed of a stainless steel shaft and a traditional copper-wound loop handle. The copper handle provides excellent conductivity for electro-stim. Needle tips are ground by automated machines, thereby ensuring perfect needle tip consistency. 
  
• Each needle 40mm (1.5") and longer is packaged in a Safe-T Sleeve, the world's first two-part guide tube. The Safe-T Sleeve was created to solve the problems that arise when inserting longer needles into dense or tight tissue - namely the potential bowing of the needle and difficulty stabilizing the needle shaft. Now you can use the Safe-T Sleeve to help complete insertion to the target depth - all without compromising the sterility of the needle shaft.
