Bundle item in Minecraft
A Bundle stores several different items in a single inventory slot, up to the space of one full stack. It is the handiest way to carry many small things, such as seeds, flowers or ores, without filling your inventory.
It is made with the Crafting Table from Leather and String.
What it does
In your inventory, pick up the Bundle and click on items to put them inside, or drop items onto the Bundle. Right click it to take an item out; scroll on it to choose which one.
Space depends on how an item stacks: an item that stacks to 64 takes very little, an item that stacks to 16 takes four times more, and an item that does not stack fills the Bundle on its own. A Bundle can even hold another Bundle.
Craft it from Leather and String, then dye it in any of 16 colors to tell your bundles apart.
