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.

Based on my visual examination of this 30-ounce stainless steel vacuum-insulated tumbler, I find it to be a contemporary utilitarian vessel designed for thermal retention. The tapered silhouette and clear lid with a silicone gasket are hallmarks of the mass-produced drinkware market popularized by brands like YETI or RTIC; however, the lack of visible branding suggests it is either a secondary-market generic version or a promotional item. The 18/8 food-grade stainless steel construction is standard for this class of item. The condition is rated as 'Fair' to 'Good.' I observed significant surface wear, including horizontal score lines and pervasive micro-scratching across the brushed finish, likely resulting from frequent use in vehicle cup holders or abrasive cleaning. These abrasions significantly diminish the secondary market value compared to a 'New' or 'Excellent' condition item. The market for such items is saturated, with high supply and low rarity, making the resale value essentially nominal. Valuation is based on local secondary market comparables for used, unbranded kitchenware. Limitations: Without physical inspection, I cannot verify the integrity of the vacuum seal or identify manufacturer stamps that may be located on the underside. Full authentication would require checking for laser-etched logos at the base and testing thermal retention properties to distinguish it from lower-quality replicas. Provenance is not a factor here, as the item is a modern commodity.
