[Mokyu]

I was wondering what is the most expensive thing on the market that i can get with 3 badges? I was thinking of:

-Pink Ribbon
-Red/White Headband
-China Buns

Anybody know?

On Ship 8:

Funny ribbon(3) sells for around 2.9mil min.
The white and red headbands(3) sell for around 3mil.
The buns(3) sell for min 3.2mil.
The varies glasses(2 badges) sell for around 1.5 mil each.

Since yer getting 10 badges when your friend hits lv 40.
You decide.
