Minecraft 1.20.1
Iron Chests Mod – Upgradeable Storage for Minecraft
The Iron Chests mod introduces several chest upgrades, expanding space and storage capacity. For instance, the iron chest alone can store as much as a standard double chest.
As you progress, you can upgrade your chest to gold, diamond, obsidian, and crystal variants. When you reach the diamond level, the number of slots won't increase further. However, the Crystal upgrade offers a unique feature – the ability to see the contents of the chest!
Moreover, this mod allows you to enhance Shulker boxes with a range of colors and upgrade options for more versatility.
