Pure Focus. Perfect Sip.
The EVERCRISE 450ml Insulated Coffee Cup is engineered for those who demand precision in every pour and clarity in every moment. Built with a food-grade SUS316 stainless steel inner liner, this vacuum-insulated tumbler delivers 6-hour heat retention and 6-hour cold preservation, making it the ideal companion for your morning commute, office sessions, and city walks alike. The SUS316 interior is highly resistant to corrosion and acidic beverages — from black coffee and lattes to fruit juices and cola — ensuring no metallic aftertaste and no compromise on flavor.
Dual Drinking Modes. Designed for versatility, the KUPUKA coffee cup features a flip-straw mode for gentle sipping and a direct-drink mode for quick hydration. Switch between them effortlessly with a one-hand operation, so you can enjoy everything from iced Americanos to hot flat whites without changing cups.
Leakproof, Portable, and Built to Last. With a 360° sealing system and a 360-degree leakproof design, this tumbler survives being tossed into your bag or hung from its braided thickened lanyard without a single drip. The silicone base pad adds anti-slip stability and protects your desk from scratches, while the frosted matte body resists wear and scratches for long-term durability.
