iFixit EU145071-1 antistatic wrist strap Blue

Prevent electrostatic damage.
Helps protect your electronics from accidental electrostatic discharge (ESD) damage during repairs. Ground yourself while working on sensitive electronics to prevent static charge build-up. Custom manufactured by iFixit for "American" sized wrists. Most anti-static wrist straps are made for use in manufacturing throughout Asia, and do not pass our ergonomics test, if they fit at all! "Rapid static dissipation by a wrist strap ground is required to prevent voltage spikes. Simple movements such as lifting one foot off the floor or raising one arm from a conductive table mat may change body capacitance by as much as 10% to 30%. Uncontrolled, the capacitively created voltage may reach several hundred volts or more.
