# Marketplace

1. #### What is the Marketplace?
   * The **Marketplace** is a feature where you can trade various items using [**Zeny**](/economic-system/currencies/zeny.md). You can trade:
     * Gear items
     * Cards
     * Gems and select materials, such as **Star Dust**
     * Some items labeled as **Not Tradeable** cannot be traded in the Market Place.
   * To purchase items, go to **Menu → Exchange → Market Place**.
   * If you rank high on the **Marketplace Trading Leaderboard**, you can earn valuable rewards.

2. **Buy**
   * Tradeable items are displayed in a collection-style interface.
   *  You can browse the item list and view items currently available for sale.
   * Purchased items are delivered via your **Mailbox**.

3. **Sell**
   * Users can list items for sale via the **Sell** tab in the **Marketplace**.
   * If the item is not sold within the specified period, the sale will be canceled and the item will return to the user’s inventory.
   * Listing an item in the **Market Place** requires [**RO Points**](/economic-system/ro-points.md).
     * If the listing period expires, the sale is canceled automatically, and the **RO Points** used will be refunded.
       * You can reclaim unsold items by clicking the **Retrieve** button in the **Manage Listings** tab.
     * To cancel a listing manually before it expires, tap the **Cancel Sale** button in the **Manage Listings** tab.
       * Note: If you cancel before the listing period ends, a portion of the RO Points used will be deducted.
   * If a sale is successful, the proceeds, minus a sales fee, will be delivered to your **Mailbox**.
