• 【100% LEAKPROOF AND SPILL-FREE】The KISSKIND 3.0 40 oz tumbler revolutionizes on-the-go hydration with its patented Twist-and-Hide straw lid technology. Engineered with precision sealing mechanisms, this vacuum-insulated cup ensures zero leaks regardless of liquid temperature - from steaming tea to ice-cold sparkling water. Its pressure-resistant design allows users to confidently toss it into bags, gym totes, or stroller compartments without fearing messy spills. The reinforced silicone gasket and locking lid mechanism create an airtight barrier, making it ideal for active lifestyles, travel, or daily commutes.
• 【TWIST-AND-HIDE STRAW LID】Innovation meets hygiene in the 360° rotatable straw cover. A simple twist completely conceals the drinking straw within a protective housing, shielding it from environmental contaminants and accidental contact. This smart design prevents dirt accumulation during transport while maintaining the straw's cleanliness. The smooth rotation mechanism ensures effortless operation with one hand, making it perfect for quick transitions between drinking and storage.
• 【STAINLESS STEEL STRAW】Prioritizing health and sustainability, KISSKIND 3.0 includes a durable stainless steel straw with food-safe silicone tip. The diameter optimizes flow for both thick shakes and light beverages, while the tapered silicone mouthpiece ensures comfortable sipping. Unlike plastic alternatives, this rust-resistant straw eliminates chemical leaching concerns and withstands repeated dishwasher cycles. The straw's polished interior prevents flavor retention and bacterial buildup.Detachable straws are easy to clean thoroughly, preventing residue buildup. Replaceable parts save costs and reduce waste, offering lasting utility.
• 【DISHWASHER SAFE】Designed for convenience, both tumbler components withstand dishwasher cycles (top rack recommended). The stainless steel body resists detergent corrosion, while the BPA-free polypropylene lid maintains structural integrity through repeated cleanings. All seals remain pliable post-wash, ensuring continued leakproof performance.
• 【DOUBLE-WALL VACUUM INSULATION】Advanced thermal engineering keeps beverages at ideal temperatures longer than competitors. Laboratory tests confirm 11-hour cold retention (0-4°C), 7-hour heat maintenance (60°C+), and 48-hour ice preservation. The vacuum-sealed chamber eliminates condensation, while copper-plated insulation reflects temperature changes. The tapered base design enhances insulation efficiency without compromising grip comfort.
• 【SLIP-RESISTANT BASE】A non-slip silicone pad integrated into the tumbler’s base ensures stability on uneven surfaces. From car dashboards to wet countertops, the grippy design prevents accidental slips and scratches. The low-profile pad complements the tumbler’s sleek aesthetic while adding functional durability.
• 【CUPHOLDER FRIENDLY】With a compact 2.9" base diameter, the KISSKIND 3.0 fits seamlessly into most car cup holders, bike bottle cages, and bag compartments. The streamlined design balances portability with generous 40 oz capacity, empowering users to stay hydrated anywhere.
