20oz Double wall vacuum insulated stainless steel tumbler. Great for hot or cold drinks. Will keep drinks warm for 3 hours or cold for 9 hours. Tumblers are dishwasher safe and plastic lids are BPA free. Black cup comes with a straight straw and the red comes with a bent straw. The reason they have different straws is because I had to purchase them from separate vendors so I could get the exact color red that I wanted. Both come custom made with the new FAB logo!
