And if not, what is? The plastic bag it came in? Anything metallic? I don't have a proper box at the moment.
Sure, why not? Earthing is usually provided by the power connection and a wooden table does not conduct electricity. Maybe make sure to discharge static current on yourself before touching it.
Anti-static bags are conductive! Don't use that or metal, or anything conductive. A wooden benchtop or desktop is ideal.
Wow, thanks for asking this ollehar! I was about to store this in a drawer inside the bag and had no idea that these are conductive or a fire risk.
