What it does

The mod changes the maximum stack size of stackable items from 64 to 67, so players can carry slightly more of each stackable item in a single slot. Items that are normally unstackable keep their single-item stacks and are not affected.

Key features

  1. Larger item stacks

    Stackable items hold up to 67 in one slot instead of the usual 64.

  2. Unstackable items unchanged

    Unstackable items such as tools, weapons and armor keep their normal single-item behavior.

  3. Works in singleplayer and on servers

    The stack change applies in single-player worlds as well as on multiplayer servers.
