Good point. Do you suppose he didn't want to disturb the wrapping? When I unwrap new old stock spark plugs I can never get them back in the box the same way.
Just Sayin.
I save the box and use the plug esp if they are a type that runs good in my engine.. There is room for everyone, but I buy for the contents not a piece of paper. Great starting price.
There was a cache of those found some time back - I've seen one out of the box and there was some apparent minor damage from dissimilar metals they are made from - cool accessory though !
