Curious Lacquered Box, Cash Shop (125)

Hello! I've returned from an extended hiatus and I'm searching through my wardrobe/galleries/vault to see if I have anything of value. I couldn't find a price for this item, it isn't posted in shops or trades. What is this worth? And how difficult would it be to sell?

Edit: Whoops, I'm sorry but I've discovered the Costume Trunk. I would still like to know if this would be difficult to sell? If this isn't the place for that, please delete.

500 CSC in the cash shop right now, pretty hard to sell, yeah

If it's hard to sell I guess the best solution is to sell the smaller l pieces separately

Thank you for the advice! :)
