oh i have seen those in stalls (i saw it selling for 500k @_@), and i also wondered whats the use of it
btw its rank 1 is correct, i took a picture of it few days ago xD , u dont have to buy from the stall to find rank, just select item and u can see it purchase list and move mouse over it to find rank
