I'd like to know if anyone has a recommendation for shipping individual PCBs. This would just be unpopulated boards, no components or other kit stuff, so there's no need for anti-static liners or the like.
The boards weigh about 0.25oz, so I was thinking of just using 1st class mail with a few pieces of light cardboard lining the envelope. Does anyone have a better suggestion? While most of the destinations would be in the US, some may be international, for which this 1st class mail idea might not work. If someone could suggest an alternative for that, I would appreciate it too.
Thanks!
