Double Layer Metal Flask

Key Features:

• Excellent Heat & Cold Retention: Made with SUS304 stainless steel and a double-layer structure, it keeps your drinks cold or hot for over 6 hours. Your ice-cold water stays at 4°F (10°C), and hot beverages remain above 50°C (100°F).
• Straw Lid for Easy Sipping: Enjoy both a normal drinking mouth and a straw mouth with a stainless steel elastic straw, designed with a silicone hose for a comfortable sip. The screw-on lid and silicone seal ring ensure it’s leak-proof and easy to carry.
• Comfortable & Ergonomic Design: The flask’s unique curves fit comfortably in your hand, with a slightly narrow base for better grip. A non-slip pad on the bottom keeps it steady, while the wide 3.0-inch mouth makes it easy to clean.
• High-Quality Materials: Made from SUS304 stainless steel for durability and corrosion resistance, plus food-grade silicone for the lid and straw, this flask is safe, practical, and long-lasting.
