Unstackable items are now weighted in a bundle as 1/4 of a full stack, or like 16 items.

There are also four new tags that can be used to further manipulate bundle interaction:

• The bundled:cannot_nest tag can be used to prevent an item from being inserted into a bundle.
• The bundled:max_weight tag can be used to make an item weigh a full stack in a bundle (64).
• The bundled:half_weight tag can be used to make an item weigh 1/2 of a full stack in a bundle (32).
• The bundled:quarter_weight tag can be used to make an item weigh 1/4 of a full stack in a bundle (16).
• The bundled:eighth_weight tag can be used to make an item weigh 1/8 of a full stack in a bundle (8).
• The bundled:sixteenth_weight tag can be used to make an item weigh 1/16 of a full stack in a bundle (4).
• The bundled:thirtysecond_weight tag can be used to make an item weigh 1/32 of a full stack in a bundle (2).
• The bundled:sixtyfourth_weight tag can be used to make an item weigh 1/64 of a full stack in a bundle (1).

Empty bundles can be inserted into other bundles, but they cannot be inserted if they have items inside of them.

On versions older than 1.21.5:

The bundle is featured in the creative menu, under the tools item group.

Bundles have a recipe, taking 6 leather and 2 string to craft.

• This recipe can be disabled or replaced by two different recipes via built-in datapacks: the original bundle recipe with rabbit hide or the cheaper bundle recipe from 1.21.2+.
