✔ In UNDECEMBER, you can purchase paid products to buy various items that help you with your gameplay.
- Purchasing products require currency such as Cash, Diamonds, Rubies, or Gold.
- Some items have a Purchase Limit, meaning they can only be purchased for a certain amount of times.
- Press the magnifying glass icon on the bottom right of each product to view the contents before making a purchase.

✔ Items purchased from the Paid Shop are saved in the 'Paid Shop Storage'.
- Each storage is divided based on the type of currency that was required to purchase the item.
- Press the 'Receive' button in the storage to send the item(s) to the bag. Received items can no longer be canceled.
- Items in storage have a storage period. Once the storage period expires, the item is deleted and cannot be reissued.

✔ Some products that are purchased with Rubies or Gold are sent directly to the bag instead of going through the Paid Shop Storage.

✔ Diamonds can be exchanged for Rubies. Rubies are used in the Paid Shop as well as the in-game Auction House to trade items with other users. However, Rubies cannot be exchanged back into Diamonds.
