This looks like a sale for 12k 30ref, but untrace of supposed buyer's side:

im not seeing anything:

13k + x ref (histories of 13 keys match, dunno about other ones):

https://backpack.tf/profiles/76561198142864294#!/compare/1626048000/1626393600 (keys clearer on buyer's side)

https://backpack.tf/profiles/76561198799636723#!/compare/1626307200/1626566400

rounds down to 13k regardless of amount of ref

13k 30ref for berliner + sweet(s) I think:

https://backpack.tf/profiles/76561198142864294#!/compare/1626393600/1626652800

rounds down to 13k

perhaps a 1:1 w/ orbiting fire capo's capper? (small sweets on each side if so):

https://backpack.tf/profiles/76561198266614530#!/compare/1626566400/1626652800

capo is also outdated, but judging off buyers at 13.2k it might be somewhere in that range, which rounds down to 13k in line with other sales.

12k sale seems low considering buyers up to 12.7k, so taking 13k.
