["Include-Centre Compatibly Infill (x1), Side Compatibility Infills (x4), Grub Screws (x10), Fin Key (x1), Reusable zip lock bag","Recovering fin sets from F1 for your new boards with F2.","This covers the gap that forms when you install original dual tab fins in an dual tab II board.","The front slot is longer in the dual tab II system, so you need this to cover part of it. It is a pretty simple system, you just slide the infill into the slot and then install the original fin as usual. It comes in and out pretty easily which makes it convenient for use in different boards."]
