This Automotive Series tumbler is a 30oz / 900ml double-wall vacuum bottle built around a gift-oriented themed print program. The wall is a five-layer construction: an 18/8 stainless steel liner (SUS 304 stamped on the base), a point solution process layer, a vacuum insulation layer, a stainless steel outer layer and a wear resistant powder coat, which the detail slices summarize as 18/8 stainless steel inside and outside with heat and cold preservation. The tapered body carries a smooth, lip-fitting cup mouth and a non slip, antiskid base.
The lid is a single 2-in-1 cover with two drinking modes, a direct drinking mouth and a suction pipe (straw) mouth whose straw flips through 90 degrees, the soft carry handle pivots on the lid sides, described in the slices as a portable silicone handle and "one cover dual use". Each unit is printed with one of ten family-role slogans in the "MY BEST... EVER / ever IN THE GALAXY" layout, grouped by body color: DAD, HUSBAND, BROTHER, GRANDPA and TEACHER on dark blue, MOM, WIFE, SISTER, AUNT and GRANDMA on mint teal. A WATERSY mark is printed near the base. The listing artwork positions the bottle for outdoor, portable and travel use.
