Red Bundle
minecraft:red_bundleA red bundle is a storage item that can hold up to 64 inventory slots' worth of mixed item types within a single inventory slot. Items stack according to their normal stack size, so items that stack to 64 take up only 1/64 of the bundle's space, while unstackable items consume the whole bundle. It is crafted from one string and one leather, then dyed red.
FAQ
How much can a red bundle hold?
A red bundle holds up to 64 slots' worth of items, with space consumed proportionally to each item's normal stack size — fully stackable items take 1/64 of the space each, while unstackable items fill the entire bundle.
Can I put another bundle inside a red bundle?
Yes, nested bundles are allowed. A bundle placed inside another bundle consumes 1/16 of the outer bundle's space plus whatever space its own contents occupy.
How do I take items out of a red bundle?
Right-click the bundle to retrieve the most recently added item, or scroll through its contents to select a different stack before withdrawing it.
