====== minecraft:max_stack_size ====== The ''minecraft:max_stack_size'' item component allows this item to stack differently. Its value, an integer, ranges from ''1'' to ''99'' inclusive. If this item component is not specified, it will make the item stack to ''64'' instead. The maximum stack size may be overridden for a specific item stack by using the [[mc>Data_component_format#max_stack_size|minecraft:max_stack_size]] data component.
