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!! Trading Method: Via Mailbox—just enter your username in the Itemku nickname column. REMEMBER!! Username, not display name (the correct username always includes an @, e.g., @FAVMART). Errors in usernames are not our responsibility. Orders will be processed when the store is open: 10:00 AM – 12:00 AM (midnight). If responses are slow, the admin is likely 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.
