Meet the DUDU Tumbler by cocosmile – your new go-to companion for flawless hydration anywhere, anytime. Designed for the modern, on-the-go lifestyle, this cup combines high-fashion aesthetics with exceptional functionality.
Key Features & Benefits:
Premium & Safe Material: Crafted from US Eastman Tritan copolyester, the cup body is entirely BPA-Free, odor-resistant, and passes stringent CTI certification. It withstands temperatures from -20°C to 100°C, making it perfect for both icy drinks and hot coffee without releasing harmful substances.
Ideal 530ml Capacity: The golden-sized capacity holds approximately 2-3 standard cups of water, reducing frequent refills while maintaining a compact, portable profile (150mm H x 110mm D, only 155g).
Ultra Leak-Proof & Sealed: Features a premium silicone sealing ring and a precision-engineered lid ensuring a 360° tight seal. Rotate or invert it confidently – no spills, no mess.
Hygienic Dust-Proof Design: The innovative food-grade PP dustproof cap with a anti-loss notch securely covers the straw opening, protecting it from dust and germs when not in use, promoting healthier sipping.
Durable & Impact Resistant: Made with upgraded, thickened Tritan material, this tumbler is highly resistant to shocks, drops, and daily wear. It's built to last.
Easy Cleaning & Full Disassembly: The wide mouth and fully detachable components (lid, straw, seal) allow for 360° no-dead-angle cleaning. The food-grade silicone straw is gentle on lips and easy to maintain.
Versatile for All Drinks: Whether it’s water, juice, soda, milk, coffee, bubble tea, or fruit-infused water, this tumbler handles it all without retaining tastes or stains.
