In the Rockets league, there are three ways to earn items to unlock every trophy related to the item. Keep in mind that each of these methods is online and you can get items:

Option 1: Play online open competition

These drops occur only within the first 10 hours of the weekly online playback time and will be reset every weekend. Keep playing until you have 5 items of the same quality or "rare items" (or higher) in your inventory. Taking this option will take a longer time to play.

Option 2: Trade with players

The quickest solution is to trade with other players. The player only needs to provide you with the goods you need or the same quality of sufficient items Buy Rocket League Items to trade and obtain better items. If you have a crate to trade, the player may provide you with valuable items (such as very rare items) in exchange for bags, so it may be beneficial to trade with the players you trade.If you do not find any player transactions, you can query for help in the Items Trading Forum topic or gaming sessions.

Option 3: Buy Crate Keys
