The purpose of deep bundles is to enable longer expeditions by automatically storing commonly found items.

Deep bundles can be open or closed, and only picks up items while open (you can tell by the enchantment glint or the tooltip). Items can only be retrieved while the bundle is closed. To open or close it, hold right click while not sneaking when it's in your main hand until it changes state. To retrieve items, hold right click while sneaking with the closed bundle in your main hand. If your deep bundle gets full, it will automatically close itself, and can't be reopened until some items are removed and it has space for more items.

While deep bundles can pick up items while they're in any inventory slot (or even your offhand), they only store items from your inventory and ignore anything in your hotbar or offhand, to allow keeping some but not all items.

Deep bundles are crafted from a specific color of bundle depending on the category, as well as a tier material. They come in 4 tiers: copper, iron, diamond, and netherite, which hold 128, 256, 512, and 1024 items respectively. They can't be upgraded to a higher tier once they've been crafted, you'll need to make a new one if you want a higher tier than what you have.

There are currently 6 bundle categories:

Digging (brown) - items you might dig up from the world with a shovel, like dirt or sand
Farming (lime) - farmable plant/animal products, like wheat, sugar cane, or raw meats
Fishing (blue) - fish and nautilus shells
Mining (gray) - items you might pick up with a pickaxe while mining, like ores or stone
Monster (red) - mob drops, like rotten flesh or string
Woodcutting (green) - logs, saplings and other items that come from trees

These categories are controlled by item tags, which can be easily changed if necessary.
