Armory

The Armory is the client interface for cosmetic items in the Steam inventory. It can be sorted and searched via keywords or customizable filters. Steam items (Steam Trading Cards, Dota 2 Invites) will not be placed in the Armory, but in the Steam section of the Steam inventory. Items in the Armory can be directly listed to the Steam Market, and Market information regarding items can be viewed in the item tooltip.

 * A default Armory comes with 10,000 slots.
 * Armory size can be increased by purchasing an Armory Expander, which grants the account an additional 240 slots (4 pages).
 * Armory size can be increased up to 34,000 slots.
 * To achieve this starting from a default Armory, one would need to use 1,000 Armory Expanders.

Filters
The armory can be filtered down to specific categories of items, which are saved to provide easy searching. Many filters are provided by default, including Rare Items, Couriers, Wards and Keys and Treasures; however the player can edit these or create their own, whenever they choose, and can be as specific as desired.
