The Waxed Oxidized Copper Chest is the waxed version of the Oxidized Copper Chest, showcasing a teal-blue surface with green highlights that represent the final stage of copper oxidation. It acts as a 27-slot storage block that can combine with another to form a Large Copper Chest with 54 slots. By applying Honeycomb to an Oxidized Copper Chest, players can create the Waxed Oxidized Copper Chest, preserving its distinct patina and preventing further weathering.

The Waxed Oxidized Copper Chest shares identical functionality with all other copper chest variants, offering the same durability, blast resistance, and storage capacity. It can be renamed, locked, or opened freely unless obstructed by a conductive block. Copper Golems can interact with the Waxed Oxidized Copper Chest to collect and move items to nearby Wooden Chests, enabling automated storage systems. The chest must be mined with a stone pickaxe or higher to drop itself, making it a decorative yet practical addition for builds featuring aged copper aesthetics.
