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 column. REMEMBER!! Username, not display name (correct usernames always include an @, 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., bathing or eating), so please be patient. We’ll do our best to respond quickly. Stock is always updated based on the owner’s inventory.
