Stainless Steel Vacuum Insulated Tumbler

This item is a 30-ounce vacuum-insulated tumbler, characterized by its tapered double-wall construction and brushed stainless steel finish. The vessel features a wide mouth at the top that steps down significantly at the midpoint to a narrower base, a design intended to fit most standard vehicle cup holders while maintaining a high beverage capacity. It is topped with a clear, heavy-duty plastic press-on lid featuring a rubber gasket for a secure seal, and a teal-colored reusable plastic straw inserted through the center aperture. The construction suggests food-grade 18/8 stainless steel, common for this style of modern drinkware. Visible condition issues are moderate, including numerous horizontal and vertical surface abrasions, scuffing, and fine scratches consistently distributed across the metallic body, particularly around the midline and base. There is a noticeable horizontal score line encircling the upper third of the cup, possibly from mechanical contact or customization attempts. No branding or manufacturer stamps are clearly visible in the current orientation, though the utilitarian style aligns with brands such as YETI, RTIC, or similar mass-market outdoor gear manufacturers from the mid-to-late 2010s to the present. The overall craftsmanship is industrial and durable, designed for thermal retention of hot or cold liquids.
