Sale for around 5 keys in paints+showstopper victory lap (25 keys)

Traded for 35 keys in mixxed pure/unusuals

https://backpack.tf/profiles/76561198083831074#!/compare/1563062400/1563148800

Buyers starting at 12 keys, sellers starting at 18 keys

Considering that there is a seller at 18 keys rn (almost half of the 35 key sale), I'm going to negate it as it possibly had money involved outside the trade window (unless I'm informed otherwise)

Therefore, based on the mp.tf and recent sale, this unusual should be priced at 25 keys.

As a bonus note, other 2 sellers are selling for 25 keys.
