It's a small nit, but after 20+ years in microelectronics reliability, I'll take the time to educate. Those gray bags are not "antistatic", they are conductive...they are meant not to ward off static electricity, but to keep everything inside them at the same electronic potential - it's the voltage "difference" between two points that causes the static "spark" and damage. If everything is at the same voltage, no spark can occur.
Antistatic enclosures/bags are usually pink plastic and usually don't offer as good of protection.
