The Waxed Copper Chest is a storage block crafted using 8 Copper Ingots surrounding a Chest in a 3×3 crafting grid, then waxed with Honeycomb to prevent oxidation. It functions identically to a regular Chest, offering 27 inventory slots, and can merge with another to form a Large Copper Chest containing 54 slots. Unlike unwaxed variants, the Waxed Copper Chest retains its bright orange hue permanently, unaffected by weathering or time.

The Waxed Copper Chest can be opened unless blocked by a conductive block, renamed with an Anvil, or locked using commands. Its durability and functionality remain consistent across all copper stages, providing a reliable and decorative storage option. Copper Golems can interact with the Waxed Copper Chest by retrieving items from it and storing them in nearby Wooden Chests, allowing for simple automation setups. It can be mined with a stone pickaxe or better to drop itself and fits seamlessly into copper-themed builds that maintain a polished aesthetic.
