The Watersy Portable Sling & Handle Vacuum Flask is an outdoor-series insulated flask built around two carry modes: a fold-down portable handle integrated at the neck and a detachable portable sling (carry strap) that clips onto lugs beside the shoulder ("TWO PORTABLE MODES OF TRAVEL", "SUITABLE FOR A SLING"). The body carries a mirror-silver "Watersy" script logo over a matte powder-coated surface with vertical fluting near the base.
The wall is a five-layer construction: 316 stainless steel liner, point solution process layer, vacuum insulation layer, 18/8 stainless steel outer layer and powder coat. The liner is stamped "SUS 316" and is promoted as odorless, non-toxic, food grade, corrosion resistant and high temperature resistant, a comparison chart shows 316 tolerating lotion, fruit juice, soup, cola, coffee, tea and soybean milk where 304 covers only fruit juice, soup and coffee.
Drinking is offered three ways: a direct drinking port through the one-click-open stopper ("elegance does not touch the nose"), the mirror-finish cup cover used as a teacup ("drink water anytime"), and the wide mouth for filling and pouring ("easy to drink and unlimited to drink"). The stopper opens with a single orange button and includes a stainless steel filter screen / tea strainer plate for tea leaves, the base has an anti-slip cup bottom that does not damage desktops. Claimed performance includes 100% leak proof, sweat-free exterior that does not burn the hand, skid resistance, and no odor or flavor retention/transfer. The wide mouth is illustrated for coffee, cola, tea, milk, beer, lemonade, milkshake and fruit juice.
Three capacities (800ml/27oz, 1200ml/40oz, 1500ml/51oz) share a 10.4cm diameter and differ only in height (23.8 / 27 / 32 cm). Four finishes are shown: solid black, solid white, and white-to-pink and white-to-light-green gradients. Listing copy positions the flask as "WARM ACCOMPANYING — LIGHTWEIGHT AND PORTABLE".
