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 enter your username in the Itemku nickname field. REMEMBER!! Username, NOT display name (correct usernames always include "@," e.g., @RzStore). Errors in 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., eating, bathing)—kindly bear with us. But we’ll always strive for quick replies. Stock is updated in real-time based on supplier availability.
