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 delivered within 10 minutes at the latest! How to Trade: Via Mailbox—just provide your username in the Itemku nickname field. REMEMBER!! Username, not display name (a correct username always includes an @, e.g., @FAVMART). Mistakes in usernames are not our responsibility. Delivery will be processed when the store is operational Hours: 10:00 AM – 12:00 AM If responses are slow, the admin is usually occupied with other activities, such as bathing or eating, so please understand. However, we will strive to respond quickly. Stock is always updated according to the owner's inventory.
