About this Mod

Non-Stackable Bundle Slots

A simple server-side Fabric mod that allows bundles to store non-stackable items
(such as tools, enchanted books, etc.) at a reduced slot cost.
Each non-stackable item now occupies 1/6 of a bundle's capacity instead of the full stack size,
allowing up to 6 non-stackable items per bundle.

This mod does not allow shulker boxes to be stored in bundles.
Compatible with vanilla clients.
