The packaging was very expensive (old German spelling), padded envelope, paper box, transparent bag with closure, again transparent bag. So far so good.
Only: both earrings were common in the latter pouches and could therefore rub aneinnander.
The bags were without all packing materials in the cardboard box and so were able to fly freely.
That has to be better off?
Both earrings thread on a small piece of thick paper or individually
in bags, the cardboard box with cotton wool or crumpled paper cushions?
Ok, both earrings were intact even upon close inspection, but could also turn out differently.
