A tapered, car-cup-friendly insulated tumbler topped by a black flip lid with an integrated pivoting carry handle. The lid serves two drinking modes from one cover: a direct drinking mouth and a suction pipe (straw) mouth, with a 90° flip-open action. The wall is a five-layer build — inner 18/8 stainless steel, point solution process layer, vacuum insulation layer, outer 201 stainless steel and an abrasion-resistant powder coat — giving food-grade, corrosion-resistant, high-temperature- and wear-resistant performance per the listing claims. Detail points highlighted: portable handle for convenient travel, smooth undeformable cup mouth that fits the lips, SUS 304 stamped inner bottom for long-term insulation and corrosion resistance, and a non-slip antiskid cup bottom. Three sizes share the same 8.6cm top / 6.9cm bottom diameter and differ only in height. Marketing line: "PORTABLE ACCOMPANYING", "AVAILABLE IN MULTIPLE COLORS".
