Alright, this has one of the trickiest suggestions that I've done.

Before saying that I don't have proof and bla bla bla, read first. Most of the sales for this one are either with hats that have outdated price or so. There are a few available on the market for low pure prices and still no takers. This suggestion today is mainly to bump the price down as there's one available at 4.5 buds (3 weeks), 5 buds (3 days), and 6 buds (2 months), long enough to not be considered a quicksale.

Sold with a hearts mongolian (0.9) for a miami tossle (7):

Note:

Miami tossle price is only 3 months, but a search on outpost shows that you can easily get it for 7 buds, so I'm taking that price at the moment

Sold for a disco cotton head (old price, but most trades on outpost having a b/o of 6):
