I must qualify what I said by saying that I've found this much harder the more specific I need to be. I could find 0 results for short M3 screws when I searched domestic sellers a few weeks ago. No hardware- or electronic stores carried them. One had them listed with a 3 month delivery and at about $3 each. After that hour+ you Amazon it, without putting hours into finding it in other countries who's languages you don't speak.

Airsoft glasses is something I can find in any mall here.
