Not sure if this is intentional or not, but the premium workshop items (I assume all of them) can be scrapped (to my knowledge, not willing to test it out.)
The main reason why I assume this is just something Nelson forgot to add is that these 2 items both came from the Unturned Stockpile and did cost money.
Nelson pls fix

If there was at least some sort of warning like with the delete button, that’d be better than what I assume is nothing.
