As Long as Ads Are Still Up = Stock Always Available If there's a 10-minute warranty label, it means your gems will be sent within 10 minutes max!! Trading Method: Via Mailbox—just provide your username in the Itemku nickname column. REMEMBER!! Username, not display name (a correct username always has an @, e.g., @FAVMART). Errors in usernames are not our responsibility. Items will be sent during store operating hours: 10:00 AM - 12:00 AM (24:00). If responses are slow, the admin may be 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 stock.
