Homebrew PCBs

This homebrew PCB holder 
<http://www.qrpbuilder.com/downloads/pcb_holder_you_can_build.pdf> was 
referenced on another email reflector. It is constructed mostly of 
polyethylene and nylon.

Is it OK to work with ESD sensitive devices using this PCB holder? Seems 
like polyethylene and nylon are good insulators which would be good at 
holding a static electricity charge?

Does it help if the PCB holder is laying on the ESD mat which I have on 
my workbench and with which I use a wristband?

Thanks.
