Upgradable Backpack

I made the backpack, which is

• Dyeable through the crafting table.
• Easily renamable using an anvil.
• Wearable in your chest slot.
• Upgradable to get more slots (9 -> 18 -> 26 slots)

How to Use Backpacks

• To store or retrieve items, simply drop the backpack on the ground. It will transform into a barrel, allowing you to manage your items. Click the "Exit" button slot to revert it to a backpack item.
