Ender Chest

Ender Chests are blocks that can store items. Ender Chests function the same as normal Chests, except that their contents are shared across all other Ender Chests placed in the world, including those placed in The Nether and The End.

Ender Chests can not be made into Double Chests and can be placed adjacent to each other normally. Ender Chests do not drop their contents when broken. Items placed inside will remain persistent even if all Ender Chests are destroyed, and can be accessed from new Ender Chests. Ender Chests have the same blast resistance as Obsidian, making them immune to explosions. They also emit light and a particle effect similar to that of an Enderman and Nether Portal. Ender Chests have an intended drawback: The contents are not player-specific on SMP. All chests share the same contents and can be accessed by anyone.

Trivia

 * As items are persistent even when all Ender Chests are broken, the player can use them to recover items from anywhere safely, even if they destroy the chest.
 * Similarly to obsidian, Ender Chests cannot be pushed byPistons.
 * By default, each server has one persistent Ender Chest inventory. This means that the player can not find an Ender Chest utilizing a different inventory of items than another.
 * It's mechanics resemble the Safe and Piggy Bank from Terraria.
 * Ender Chests could potentially be used a sort of mailbox on multiplayer servers, where a Written Book would be used as the mail.
