How to Upgrade a Vanilla Shulker Box to Copper

Craft the Vanilla to Copper Shulker Box Upgrade

Place a Vanilla to Copper Shulker Box Upgrade in a crafting grid together with the shulker box you want to convert. The upgrade item is the only conversion component you need; the result is a Copper Shulker Box.

What You Get

A Copper Shulker Box stores the same contents as the box you upgraded. Any items already inside are preserved through the conversion. Once you have a Copper Shulker Box, you can keep pushing it up the material ladder with the matching upgrade items.

Planning the Ladder

Copper is the first rung. From there the upgrade chain continues through Iron, Gold, Diamond, Crystal, and Obsidian using the named upgrade items: Copper to Iron Shulker Box Upgrade, Iron to Gold Shulker Box Upgrade, Gold to Diamond Shulker Box Upgrade, Diamond to Crystal Shulker Box Upgrade, and Diamond to Obsidian Shulker Box Upgrade. Decide your target tier before you start so you do not waste upgrade items on a box you will replace.

Dyeing After Upgrading

Every material tier exists in all sixteen dye colors, from White Copper Shulker Box through Black Obsidian Shulker Box. If you want a specific color, dye the box at the tier you plan to keep, since the color variants are separate blocks and items.
