The Watersy Portable Car Cup is a 30oz (890ml) vacuum-insulated stainless steel tumbler designed for vehicle use, with a straight upper body stepping down to a narrower 70mm base that fits car cup holders. The source detail page names it "" (portable car cup) and lists it under the product-info block as "" (car cup). Construction is a five-layer temperature-lock wall: outer spray-paint finish, vacuum insulation layer, 304 stainless steel inner liner, 304 stainless steel outer wall and electrolytic polishing on the inner surface, the inner base carries a stamped "SUS 304" mark and the rim is smooth and burr-free. The fitted lid is a clear AS-resin slide lid, and a straw is supplied so the cup supports multiple drinking modes ("one cup, three drinks"). Advertised performance includes 12h hot/cold retention (measured on the source test panel as ≥52°C after 8h and ≥40°C after 12h for hot, ≥5°C after 8h and ≥8°C after 12h for cold), 360° leak-proof sealing, BPA-free food-grade materials, and an outer coating that survives 25 dishwasher cycles. The body carries a laser-engraved WATERSY logo. Eleven colorways are shown: dark green, yellow, light green, tender pink, rose red, white, turquoise, mint green, brushed stainless steel, black and orchid pink. The page also markets factory certifications (LFGB, BSCI, FDA, SEDEX plus an ISO/CE/RoHS/GS/RCS/BPA-free badge row) and a full DIY customization program covering lids, packaging, logo techniques and surface finishes, with small-batch orders accepted.
