► How to use inventory Expanders:
1. Open TF2 game and click on the "Backpack" icon in the main menu to access your inventory.
2. Click on the "plus" icon located in the upper right corner of your inventory.
3. In the pop-up window, you'll see the option to purchase a backpack expander.
4. Click on the "Buy Now" button and follow the prompts to complete the purchase using funds from your Steam wallet.
5. Once the purchase is complete, go back to your inventory and click on the "Use with..." button next to the backpack expander.
6. Select the backpack you want to expand and click "Use".
7. The backpack expander will expand your backpack by 100 slots.
8. You can purchase multiple backpack expanders to further expand your inventory. Note that backpack expanders are a one-time use item, so you'll need to purchase additional expanders if you want to continue to increase your inventory capacity.
► If you want to keep more items in your inventory than number of maximum slots:
You can move your items to the Steam Market (put higher price so nobody not buy it) and you can receive more items by trade and put it to Steam Market again multiple times, after you remove your items form Steam Market you can keep even more than 4000 items at your inventory now. But I don't recommend setting a very high price for your items, so as not to attract too much attention, just a little higher.
