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 10 minutes at the latest!! How to Trade: 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). Mistakes in usernames are not our responsibility. Delivery will be sent when the store is operational. Hours: 10:00 AM - 12:00 AM. If response is slow, the admin is usually occupied with other activities, like bathing or eating, so please understand. But we will strive to respond quickly. Stock is always updated according to the owner's stock.
