As Long as Ads Are Still Up = Stock is Always Available If there's a 10-minute warranty label, it means your gems will be sent within a maximum of 10 minutes!! Trading Method: Via Mailbox—just provide your username in the Itemku nickname field. 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 when the store is operational: 10:00 AM - 12:00 AM (midnight). If responses are slow, the admin might be occupied with other activities, like showering or eating, so please understand. However, we will strive for quick responses. Stock is always updated according to the owner's stock.
