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

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

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.
