Okay so I bought deus specs and a fast learner for 3.74 € and apparently both items are for some reason clean and instantly tradeable...
Thanks Tf2 shop
valve updated the mann co store earlier this week iirc (TWO WEEKS AGO) to make all items bought craftable
that makes uncraftables worth just a tad bit more
as for instant tradeability, that may be due to the holidays and valve wanting people to buy as many keys as possible
