It’s a black BPA-free bottle with a durable stainless steel construction. Features double wall vacuum insulation (‘TempShield’) that can keep beverages cold up to 24 hours and hot up to 6 hours. Has a wide mouth and flip lid (but note that the lid is designed to reduce spills rather than be completely leakproof). Used only a few times so in great condition. 16 oz.
