BackPack Add-on 1.21+/1.19+

When the regular inventory is no longer enough, a solution comes to the rescue. Forget about lack of space — BackPack allows you to take everything you need on your journey. In this mod, additional storage, a convenient interface, and crafting from basic resources are provided, and in Minecraft PE this means more freedom for adventures.

You will now get 27 new slots that can always be filled with Rotten Flesh, Cobblestone, Sand, and Gravel. Crafted from Rope, Leather, and Wool.
