I was going to put this in the little things topic, but I don’t see it, so I’ll put it here.
Vanguard Dust Pack
514 Plex
1 resonant key
Make it an in game EVE Online item
Activatable to unlock Vanguard access
Market tradable
This will put the price above the $15 founders pack but this will be purchasable for EVE players with PLEX or directly on the in game market from other players with ISK.
