As Long as Ads Are Still Up = Stock 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 (correct usernames always have an @, e.g., @FAVMART). Errors in usernames are not our responsibility. Delivery will be made 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’ll try to respond quickly. Stock is always updated according to the owner's stock.
