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 the 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). Delayed responses may occur if the admin is occupied (e.g., bathing or eating)—please bear with us. We’ll still strive for fast replies! Stock is updated in real time based on supplier availability.
