🧩 What is Probably Backpacks?
Probably Backpacks adds a complete Back slot to your server. Players craft backpacks from Leather all the way up to Netherite — each tier offering Back slot and Back slot. Backpacks are equipped in the CuriosPaper Back slot and are visible on the player's back as a 3D model!
This plugin is a CuriosPaper addon — it hooks into the accessory system to provide a seamless backpack experience with custom textures, recipes, and a rich upgrade system.
