Any idea how much this has previously sold for?

it's currently available in the cash shop for 125 csc, so it's worth approximately 1.25 times the current going price for a 100 credit gift card, more or less. so like, 13-15 million. but most people would rather just buy the csc and then buy the item from the cash shop, so if you're hoping to sell for sP you could knock the price down a little.

Thanks Frenchi. I was just reading that we can stock csc items in our shops and ask for csc instead of sP but I don't see how to change the currency. Would you happen to know anything about it?

you can only do that for custom wearables (items with rarity 200).

Oh, ok. Thanks!

Also a quick note, you can ping other users (make a notification pop up on their Events tab) by typing their username after a @ or clicking the first icon in the blue bar above the user's post, which resembles a megaphone speaker. That way, they are able to know when you last talked to them! Otherwise, if they don't constantly check back, it's impossible to know. This makes life easier, you know :)

Thanks for telling me how to ping properly! I tried it before and pinged myself. lol

trust me, it happened to all of us :) Best of luck!
