If anyone wants to know the % chance of the different event stones/bells:
Love Bell (black): 50%
Friendship Bell (white): 40%
Faith Bell (blue): 10%
(I opened like 5k boxes and got 49,9% + 40,0% + 10,1%)
The chance of getting Love and Friendship bells are 4x and 5x of the chance of getting Faith, and the price of Faith is like 10x - 50x higher
