Black knee star? From the aniversary stars Its rarity 150 and nothing in usershops

Well, keeping in mind that it comes from an item that can be found free around the site, I don't think it's worth a lot. You would be the first to price it obviously, but I think 250k would be an okay price to start with.

If they keep the items up like they normally do, they'd probably drop to 5k :D

Locking, as this is priced in the shop search now.
