This Watersy automotive-series tumbler is a double-wall vacuum insulated cup built with an 18/8 food-grade stainless steel liner and outer wall, finished in a sweat-proof powder coating. The listing slice set presents it as a "STAINLESS STEEL TUMBLER" in four capacities — 10oz/296ml, 20oz/591ml, 30oz/887ml and 40oz/1183ml — under the heading "MULTIPLE CAPACITIES & COLORS". The tapered lower body is shaped to sit in standard vehicle cup holders. Each purchase includes two lids and two straws: the main lid accepts a straw, flips open for direct drinking, and closes with a push cover, sealed by a silica gel O-ring with a rounded easy-open corner, a straight and a bent stainless straw plus a cleaning brush complete the set (/.jpg). Marketing claims on the slices include 100% leak proof, sweat free / not burn hand / skid resistance, no odor and no retention or transfer of flavor, long-term hot insulation and long-lasting cold insulation. Factory quality assurance badges shown are BSCI, FDA and LFGB, with a certification row listing LFGB, FDA, BSCI, IS9001 and CE alongside certificate thumbnails (Intertek, SGS, amfori, ISO9001:2015 registration). Nine colorways — solid black, mint, pink, red and blue plus four gradient two-tone finishes — are offered across the four sizes (color subfolders and swatch column, /1.jpg).
