Hey, any sales within the past 3 months are fair game. Anything older than that is outdated

Sale 4

Yours, already listed above.

You might wanna go with 30 keys flat here since the 48 is a bit too outdated

Your item shows it was traded 4 times in the last ~20 days (https://backpack.tf/item/12713422431), you would have to check out those sales and maybe check for others that happened on one of the other 3 scorching brain buckets that exist according to backpack.

The sale from last year is way older than 3 months and can not be used anymore.

If all the other sales can not be used because they are bulk/untrace you could just suggest this at 30 keys flat. Considering buyer that seems pretty low but should work.
