The WB5600 Series anti-allergy wrist band set is the ideal grounding device for people with allergies to common metals. It features hypoallergenic silver-plated nylon thread for conductivity and the back plate has a plastic cover so that metal does not come in contact with skin. This maroon colored wrist band and coil cord set features a 360 degree conductive contact around the wrist, providing maximum skin contact while allowing the skin to breathe. The band is standard with 4mm male snap. The 2.5mm polyurethane coil insulation offers excellent coil memory.
