VICKNIY’s 32oz tumbler comes with a surprisingly complete accessory kit. You get a two-in-one lid, two stainless steel straws, a cleaning brush, a protective cup mat, spare O-rings, and four silicone straw tips. That is everything you need to use and maintain the cup from day one, no extra purchases required.

The double-wall insulation keeps drinks cold for hours without sweating on your hands or desk. The lid flips up for chugging or seals tight for straw use, and the thumb tab makes one-handed operation easy during a commute or while working. At 32 ounces, it holds enough water to get through a morning meeting or a trip to the beach without refilling. The silicone boot on the bottom adds grip and protects surfaces from scratches.

The lid is spill-proof when closed, but it is not completely leak-proof if you toss it sideways in a bag. For desk use, car rides, and outdoor days, it works reliably. The included straw brush and spare seals show VICKNIY expects this cup to last through regular washing and daily abuse.
