27oz vacuum insulated 18/8 food grade stainless steel cups with BPA free lids that keep your drinks hot or cold all day. They have a laser etched drawing I did of a Model X on the side with the falcon wing doors open. $35 shipped for the 27oz, $30 shipped for the 10oz. The 27oz fits the Tesla cupholders great, the 10oz will not fit the Tesla cupholders as it is wider at the base.
