Shulker Box

A shulker box is a block that can store and transport items.

Breaking
Shulker boxes can be mined with any tool or by hand, but using a pickaxe is the most effective. Shulker boxes drop themselves when mined. Unlike other containers, the contents of shulker boxes are stored within the dropped item, and not dropped separately. When instantly mined in Creative mode, shulker boxes drop as an item if there are items stored within, unless is set to "false".

Usage
A shulker box has 27 inventory slots, the same as a chest.

Shulker boxes are portable chests: they keep their items when broken, which can be retrieved when placed again. This is different from other containers, which drop their contained items as item entities when broken. A shulker box drops itself as an item if pushed by pistons or destroyed by an explosion. When a shulker box with items inside is held or in a container's inventory, the items are listed as properties.



A shulker box's items can be fed or removed by a hopper.

Shulker boxes can be stored in all containers except for other shulker boxes and bundles.

When placed on a wall or ceiling, shulker boxes face and open sideways or upside-down, respectively. Shulker boxes cannot be opened if a solid opaque block is on their top surface, similar to a chest. For example, if a shulker box is facing upside-down and a solid opaque block is below it, the shulker box cannot be opened. A shulker box can also be placed using dispensers.

Like a chest, a shulker box requires a transparent area above to be opened, and it opens only if the hitbox of the top of the open shulker box does not intersect with another hitbox. This way, a shulker box can be opened with an upside-down slab or an upper trapdoor on top of it. It is also unique in that when opened, its hitbox expands to 1.5 blocks high/wide, physically pushing entities where it is facing.

By default, the GUI of a shulker box is labeled "Shulker Box", which can be changed by naming it in an anvil or by changing the  tag using the  command.

Undyeing
Dyed shulker boxes can be undyed using a cauldron. To do this, a dyed shulker box on a cauldron that has water in it. This causes the cauldron's water level to decrease by 1, and the shulker box loses its dye color.

Piglins
Piglins become hostile toward players who open or mine shulker boxes.

Trivia

 * With 37 shulker boxes in a player's inventory, hotbar and off-hand slot, 999 stacks of up to 64 items (up to 63936 total items) can be held. With 36 shulker boxes and an ender chest with 27 shulker boxes in it, 1701 stacks (up to 108864 items) can be held.
 * With strength value 5 llamas, each caravan of 10 llamas with inventories full of shulker boxes can carry up to 4050 stacks (up to 259200 items).
 * When the camera is far enough from a shulker box, the shulker box is invisible, even though it is still within the render distance, this is because the shulker box is still considered a mob.
 * In snapshot 20w45a shulker boxes mimic the movement of a shulker opening and closing its shell.
