WARNING: You can only use 100 slots in your cash inventory. Please be aware of how many boxes you are buying since you can have more than 100+ items BUT you would not be able to open boxes.
For ex, you have 10 cash items in your inventory, you should only buy 37 SSBs. Why 37 and not 38? Because you need 1 slot to open them.
Reward List for Surprise Style Boxes (SSB)
Please ignore the character/s being naked. :^(
Pray to RNGesus.
SSBs are evil.
Bless you and your NX.
