# 1. What is a Storage?

In the storage room, you can see all the Miners and Parts you have and track your progress in collections and sets!

Here you will find four tabs:

1. [<mark style="color:green;">Inventory</mark> ](https://rollercoin.com/storage/inventory)— Items that you have not used yet are stored here.
2. [<mark style="color:green;">Collection</mark> ](https://rollercoin.com/storage/collection)— Here, you can view the miners you've received and merged, as well as the ones you have not yet.
3. [<mark style="color:green;">Sets</mark> ](https://rollercoin.com/storage/sets)— Here, you can check out miner and rack sets to receive certain bonuses for completing them with Miners.
