Shulker boxes are special storage containers in the game Minecraft. They are unique because they can hold items like regular chests, but they also retain their contents when broken and picked up. This makes them very useful for organizing and transporting items. To craft a Shulker box, players need a chest and a Shulker shell, which can be obtained by defeating Shulkers, a type of enemy found in End Cities. Shulker boxes come in various colors, allowing players to easily identify different storage boxes based on their contents.
