The E-series ergonomic-handle tumbler (internal code "E", marketed in Chinese as "E") is a 1200ml car-cup-format insulated tumbler with an integrated rectangular carry handle and a contrasting color-block collar under the lid. The body uses a five-layer temperature-lock wall: an outer spray-paint coat over a SUS304 stainless outer wall, a vacuum insulation layer, a SUS316 stainless inner liner finished with an electrolytic polishing process. The detail page claims 12h vacuum hot/cold locking, with measured test values of ≥52°C after 8h and ≥40°C after 12h for hot drinks, and ≤5°C after 8h and ≤8°C after 12h for iced drinks. The PP lid is one-press open and is promoted as "one cup, three ways to drink" (straw plus flip-open drinking openings), with a 360° leak-proof seal and a twist-to-carry lid ring, one handle and one straw are included per piece. The wear-resistant sprayed outer layer is stated to survive 25 dishwasher cycles, and the product is BPA-free food-grade material. Three two-tone colorways are shown (green/cream, pink/blue, cream/yellow). The detail page also offers DIY customization: packaging, logo (seven printing/engraving techniques) and surface finish (twelve finishes), and states small-batch orders are acceptable.
