Upon purchasing this package, you will be given the Summer vKit Shard in-game on Factions: Pirate. Redeeming this vKit Shard will give you the contents of the Summer vKit as well as a chance to unlock the vKit permanently. 

Every attempt at unlocking the vKit will increase its chance of success by 5%! If you unlock the vKit, it will be unlocked permanently; if you do not, you will only be given the contents one time (Level 3 version). This vKit has a 72 hour cooldown when unlocked.

Any item above that doesn't have a listed "chance", is given 100% of the time.
