I have a Chroma Suit with an illegally-attached Tails Tails accessory that I put on it back when rear slots didn't exist (possible attachment window is somewhere around February-June 2012), and someone recently made an offer for it. This piece means a lot to me, so I don't particularly want to sell it, but I will if I get an offer that I can't refuse. But I'm not sure if the offer I'm looking for is even ballparking what it's actually worth. Does anyone have any idea? This is the only one in existence, as far as I'm aware.
