As Long as Ads Are Still Up = Stock Always Available If there's a 10-minute warranty label, it means your gems will be delivered within 10 minutes max! How to Trade: Via Mailbox, just provide your username in the Itemku nickname field. REMEMBER!! Username, NOT display name (a correct username always includes "@", e.g., @RzStore). Incorrect usernames are not our responsibility. Orders will be processed during store hours: 10:00 AM – 12:00 AM (GMT+7). If responses are slow, the admin may be occupied (e.g., showering or eating)—kindly bear with us. We’ll do our best to reply promptly. Stock is updated in real time based on supplier availability.
