Ender Chests are special storage containers in the game Minecraft. They allow players to store items securely, and the contents are accessible from any Ender Chest in the game. This means that players can share items across different locations without the risk of losing them. When a player places items in an Ender Chest, those items are linked to their unique Ender Pearl identifier. This feature makes it easy to transport valuable resources, as players can access their stored items from any Ender Chest they encounter, regardless of where they are in the game world.
