3 Cup 500ML Double-Layer Stainless Steel Vacuum Flask Set | Hot & Cold | Random Color

This elegantly packaged set features a primary vacuum-insulated bottle and typically includes two or three matching cups, all crafted from stainless steel and presented in a sleek gift box. The design prioritizes both functionality and aesthetics, making it suitable for various settings from outdoor adventures to professional environments.

• Superior Temperature Retention: The core feature is its double-wall vacuum insulation, which creates an airless space between the inner and outer stainless steel walls. This significantly minimizes heat transfer by conduction, convection, and radiation, effectively keeping drinks hot for up to 12 hours and cold for up to 24 hours.
• Premium Material: Constructed from high-quality, food-grade stainless steel (often 304 grade), ensuring durability, rust resistance, and safe usage without imparting metallic tastes or odors.
• Leak-Proof & Condensation-Free: Designed with a secure, leak-proof lid and seal (often featuring silicone gaskets), preventing spills and messes. The vacuum insulation also eliminates condensation on the exterior, keeping surfaces dry.
• Convenient & Portable: With a common 500ml capacity, the flask is an ideal size for individual use and fits easily in most bags, car cup holders, or backpack pockets. The inclusion of multiple cups makes it perfect for sharing.
• Versatile Use: Suitable for a wide range of beverages, including hot coffee, tea, or soup, and cold water, juice, or iced tea. It's perfect for daily commutes, office use, outdoor activities like hiking or camping, travel, and fitness routines.
• Gift-Ready Presentation: Packaged in an attractive gift box, making it an excellent and thoughtful present for various occasions like birthdays, holidays, or business gifts.
• Easy to Clean: The stainless steel material and often wide-mouth design facilitate easy cleaning, ensuring hygiene and longevity of the flask.
