This 40oz (1182ml) travel tumbler combines a vacuum-insulated double-wall body with a large ergonomic carry handle. The wall is built in five layers: an 18/8 stainless steel liner (SUS 304 stamp on the base), an electrolytic process layer, a vacuum insulation layer, a stainless steel outer layer and an outer powder coat layer. The lid works two ways: it accepts the included PP straw, and a flip-up / rotating silicone-sheet cover exposes a straight drinking mouth, making it a dual-drink cup. The wide mouth allows easy filling with ice and drinks such as coffee, cola, juice, milkshake, tea, milk, beer or lemonade, and hot/cold icons indicate both hot and cold use. The tapered cup bottom fits vehicle cup holders ("CUP HOLDER FRIENDLY"), and the listing imagery places the tumbler in car, yoga, running, riding, camping, beach and hiking scenes. The handle carries an anti-slip silicone insert and is described as ergonomic and comfortable to hold. Ten matte powder-coated colorways are offered. Dimensions: 27.5cm tall, 10cm top diameter, 7.5cm base diameter, 12.7cm handle, weight 524±10g, measured manually.
