https://backpack.tf/profiles/76561197965949373 It went here, but the backpack is private

Sold for $350 Paypal + $100 in the form of a Strange Neo Tokyo War Paint Factory New bought from SCM

Screenshots by the buyer, I reuploaded them to Imgur because Steam screenshots expire: https://imgur.com/a/WG1oU3w

The paint was directly used to replace $100 Paypal: https://gyazo.com/b01400b60a7021870cf189de85d2880e

Instead of taking the paint's price, I'll price this as if it was bought for $450 Paypal.

Paypal key sales are borrowed from the open refined suggestion.

Taking Paypal key rates at $1.68-$1.77 ($1.725), the Minigun comes to $450/$1.725 = 261 keys, rounding to 260 for any variances in key price
