Requested by the buyer so here we go :)

Looks like there's only one recent sale at 325 pure, here's the item's history: https://backpack.tf/item/983971360

The trade was a bit wonky so I'll explain what happened. The buyer accidentally only bought 319 keys and sent an offer with 319 pure for the hazmat. I informed them the offer was short 6 keys and they asked me to send a counter offer back to them while they bought the remaining 6 keys. To send the counter, I removed the hazmat from the trade offer. I think the buyer accidentally accepted that offer, which at that point just had 319 keys for nothing on my side, so we completed the trade by doing just the 6 keys for the hazmat. In total, that's 325 pure.
