Safest shipping option for high value instruments in General Concertina Discussion Posted Tuesday at 07:24 PM This has been discussed before, but the answer is always changing as the parcel delivery industry changes. What's the best/safest mode for shipping high value concertinas - in the US, to US destinations? Years ago, Paul Groff argued that the safest way was the US postal service registered/insured mail - the service that required every edge of the box to be taped; the postal employees then stamped along all the edges. But I don't know if that's still the safest. I don't mind paying for a high level of security. Suggestions?
