I have custom laser etched Model X 10oz and 27oz vacuum insulated tumblers. These keep coffee hot for hours, and ice all day. The 27oz fits perfect in the Tesla cupholders (I have a P85, and mine goes everywhere with me). The 10oz will NOT fit most automobile cupholders. $30 shipped for the 10oz and $40 shipped for the 27oz. You can message me to order. I will be taking orders until July 10th, at that time will produce and ship orders.
