As Long as Ads Are Still Up = Stock Is Always Available If there’s a 10-minute warranty label, it means your gems will be delivered within 10 minutes at the latest! How to Trade: Via Mailbox—just enter your username in the Itemku nickname column. REMEMBER!! Username, not display name (the correct username always has an @ symbol, e.g., @FAVMART). Mistakes in usernames are not our responsibility. Orders will be processed during store operating hours: 10:00 AM – 12:00 AM (midnight). If responses are slow, the admin may be occupied with other activities, such as bathing or eating, so please understand. However, we will do our best to respond quickly. Stock is always updated according to the owner's inventory.
