Your Infinibag is where all your collectables are stored on MCC Island, sorted into five different tabs:
Everything - Contains everything.
Consumables - Contains all your consumables.
Blueprints - Contains all your blueprints.
Materials - Contains all your crafting materials.
Miscellaneous - Contains everything not sorted by the other pages.
The Infinibag does not store certain currency such as 
Coins and 
Gems, but does display the counts on the right-hand side of the Infinibag's GUI.
You can access your Infinibag in any lobby by right clicking with its item in your hotbar or by using the command /infinibag.
