compare link on buyers end is stuffed up and it says obtained together, how do we know that those other keys werent traded quickly, which most likely where , not appearing on buyers end

S. Sandvich and S. PDA must have been traded for keys before the Unu's trade (2 days gap in buyer's history, that's definitely not accurate when basing a suggestion on items' histories)

IDs of the 60 keys have a similar serial number within a 500-600 range, they're part of the same trade offer !

Best here will be to add one of the traders for a screenshot, but it is almost certain it sold for 60
