The Stack Extending Backpack is a magical bag with 54 extra storage slots that permanently boosts any item’s stack size to 99—even normally unstackable tools, weapons, and armor. Right-click while holding it to open its GUI, then drag or shift-click items into the grid; once they’ve touched the backpack, they’ll always stack to 99 everywhere. It can’t be placed in the world or stored inside another backpack, so your expanded, forever-boosted stacks stay safe and convenient.
