BackPack
Tiered portable storage for Paper
Carry more. Place it down. Upgrade it. Keep everything.
BackPack adds craftable, upgradeable bags that work like a mix between a shulker box and a real inventory. Right-click to open, place them in the world as chests, break them and your items stay inside — no drops lost, no empty bag.
Features
Five tiers
| Tier | Capacity | Pages | How to get it |
|---|---|---|---|
| Tier 1 | 27 slots | 1 | Chest in the center, 8 logs around |
| Tier 2 | 54 slots | 1 | Tier 1 in the center + 8 iron ingots |
| Tier 3 | 80 slots (53 + 27) | 2 | Tier 2 in the center + 8 gold ingots |
| Tier 4 | 106 slots (53 + 53) | 2 | Tier 3 in the center + 8 diamonds |
| Tier 5 | 210 slots (53 + 52 + 52 + 53) | 4 | Smithing table: Tier 4 + Netherite Upgrade + Netherite Ingot |
Multi-page GUIs (Tier 3+)
- Bottom-left: ← Previous Page
- Bottom-right: Next Page →
Navigation buttons and fillers cannot be taken or moved.
Open & place
- Look at the air → right-click → open the backpack inventory
- Look at a block (or sneak) → right-click → place as a chest
- Break the placed chest → the backpack item returns with all contents
Safety
- You cannot put a BackPack inside itself
- Contents are stored on the item (shulker-style persistence)
- Bundle appearance, but not vanilla bundle behavior — it will not open as a real bundle

Crafting
- Tier 1 — Crafting table: chest in the center, 8 logs around
(Oak, spruce, birch, jungle, acacia, dark oak, mangrove, cherry, pale oak, crimson, warped, and wood/hyphae variants) - Tier 2 — Tier 1 in the center + 8 iron ingots
- Tier 3 — Tier 2 in the center + 8 gold ingots
- Tier 4 — Tier 3 in the center + 8 diamonds
- Tier 5 — Smithing table: Tier 4 + Netherite Upgrade Smithing Template + Netherite Ingot
Upgrades keep the same backpack identity and move existing items into the larger storage.
Requirements
- Paper (or a Paper-compatible fork) 1.21+ / 26.x
- Java 21+ on the server
Install: drop the jar into plugins/, restart the server, craft your first bag.
Notes
- Built for survival and economy servers that want portable storage without replacing shulker boxes.
- Placed backpacks use a chest block; breaking it always returns the backpack item with inventory intact.
- English UI and messages by default.
