Beekeeping Stainless Steel Tweezers are made of high-strength stainless steel with anti-static non-magnetic paint on the surface, and acid-base protection. Please put the protective tube back on the sharp tweezers for safe. These ESD Tweezers are set with ESD (Surface Electrostatic Discharge) finish protecting the components and handles from the damaging effects of static. These electronics tweezers can adapt to long-term work with the appearance of smooth lines and fine processing.
