Not sure if they are worth that much, tbh. Promo items lose their rarity very quickly. I'd suggest trading it for a good/decent long collar. I don't want it, but I'm just telling you. :)

it's worth more than a black long. They're having a good trade.

i want one buddy me if u want to see what i have for it but im sorry but my 2 black longs and 3 founders and one tan hd got scammed btw im pavol7 :P
