Id say try your luck with 25 mil to 30 mil? xD

Add up what all of the items inside cost.

Some people collect the boxes, so possibly higher.

or you could add those both prices and have the average? xp so 20.24 mil? x)

It's probably going to be worth a little more than the cost of the items since there are collectors who won't want to open it.

25mil is a good idea IMO

I say around 25mil.

By the way, the gothic loli wig was around 4mil on shop search last time there was one.
