Minecraft wiki entry for Tips_and_tricks, associated text: Late in the game, you can craft shulker boxes to store extra items later on in the game. These shulker boxes can then be stored inside an ender chest. Color code the shulker boxes to create an organized inventory. This basically gives you an extremely large backpack that keeps your items after death. Note that the shulker boxes are only safe if they're actually in the ender chest (or somewhere safe) when you die because they can still despawn like any other dropped item!
