Infinite Storage - Boundary-less Storage for Minecraft
This mod introduces unique containers with nearly limitless capacity to the game. You get a magical bag and an enchanted chest, each containing 27 item slots. The key feature is that each individual slot can hold an enormous quantity of identical items - up to the maximum Integer value in Java.
