Got it from the Free Shop.

Its super pretty, but doesn't fit my style at all. Was wondering how much they usually run?

That comes from , which is available for 250 CSC in the Cash Shop every April & ~35mil is shops at the moment.

250 CSC is about 13mil sP right now (the conversion rate is a bit deflated rn.. 100 CSC usually goes for around 8mil).

I've seen collection items listed lately for between 100-200 CSC & 10mil-25mil. Im not sure how in demand that particular backdrop is; you might start with the current collection box price & haggle from there. Hope this helps c:
