Quoted from Waxx:The Stern shaker is $99 at PBL.

Edit: I also own sheets of Invisiglass that I move to my new pin when I sell or trade. When I buy Invisiglass for $200 I get to keep it. When you sell an LE they are going to want the HD glass.
LEs look great and buy them if you want but the gameplay isn’t different than a Premium.
The PBL shaker is theirs not a stern but nearly identical and works the same. have OE in my IMDN and PBL in JP
