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 max! How to Trade: Via Mailbox—just provide your username in the Itemku nickname column. REMEMBER!! Username, not display name (the correct username always has an @, e.g., @FAVMART). Incorrect 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 may be occupied with other activities, such as bathing or eating, so please understand. But we’ll do our best to respond quickly. Stock is always updated according to the owner's stock.
