Durable stainless steel black mug with vacuum insulation. - Brand: YETI - Color: Black - Material: Stainless steel - Features: Vacuum insulation - Capacity: 14oz (approx. 355ml) Thank you for viewing. This is a YETI 14oz tumbler. I purchased it at an outdoor shop in the US and used it a few times at home. I've been storing it since then, so I'm selling it to declutter. It's large and convenient for both home and camping use. Thank you.
