How To Safely Ship Cartridges For Retip

Now I am not worried about securing them in the box, I got that part down.

What I am worried about is safe and timely arrival. I am shipping a Transfiguration Proteus and ZYX 4D for replacement diamonds, probably to VAS. The MSRP of these two cartridges was $10k when new, in used condition certainly the value is lower. But if they are lost I would essentially spend equivalent to MSRP for like replacements.

How do you ship and insure high dollar items such as this? Given the recent news about USPS I am hesitant. Although I was thinking of using a registered parcel, but I don’t think I can insure for a significant amount. FED EX is what I typically use, but their capacity seems to be maxed out these days, and packaging takes some odd routes.

Anyone have any tips they are willing to share about sending a small and light but high value package these days?
