And what does that have to do with the explanations provided so far?
>>Space it away from the lid for the drop test.
Bizarrely, As stated, it's an auction= a photo of an item (actually 2 the same but I spared you the duplication) for sale (that I was interested in bidding on) so what "drop test" can be done and why I do not know.
So, bizarrely, I found no use in the comment/ observation/ instruction.
I don't see bulk auctioneer sellers doing "drop test" or "spacing" for bidders any time soon.
Large silvery spherical object light reflections on the outside of what should be I thought black trucks clearly in approximately adjacent juxtapositions was a concern. I regret...
