# Introduction

Items can be used in Carda Station to gain different effects and advantages including additional abilities, access to certain areas or decorative accessories. 

All items are stored in the blockchain and can only be used once a wallet is connected to your account.

With the goal of interoperability in mind, Carda Station implements inventory items that are created by external projects as well.

### Supply of Inventory Items

Inventory items have different maximum supply which in turn give them different rarities. Generally, lower supply means they come with better features compared to items with higher supply. The rarity system is as follows.

| Rarity    | Max Supply |
| --------- | ---------- |
| Common    | 100,000    |
| Uncommon  | 10,000     |
| Rare      | 1,000      |
| Epic      | 250        |
| Legendary | 100        |
| Fabled    | 10         |
| Astral    | 1          |
