Minecraft wiki entry for Defeating_an_End_city, associated text: Shulker shells are useful. Keep as many as you can, and using the chests from in the cities, you can create shulker boxes. It is recommended to store stackable loot separately from the non-stackable loot. You may only need one shulker box to store the stackable items, but you will definitely need more than one shulker box for non-stackable loot. If you really would like to go on a spree, you can clear out your ender chest, as these can hold boxes too. Since the chances of death and/or getting lost are so high, it is best to store your loot in an ender chest. Unfortunately, recursive tactics don't work here, as shulker boxes cannot hold shulker boxes. However, the combination of shulker boxes and an ender chest allows for a quick and easy way to get home via the void.though you will lose your exp doing this and it doesn't work on hardcore).
