Smart Back Packs Mod gives you a flexible inventory system that grows with your adventure. It starts as simple storage but can turn into a portable machine with the right upgrades. You can wear these bags on your back or place them on the ground like a block. The mod lets you add magnets, auto-feeders, and even crafting tables right inside your bag. It is a great way to keep your items safe and organized while you explore the world.
