Gululu Ice Ba Ring Vacuum Flask

The Gululu Ice Ba Ring Vacuum flask features a 316L antibacterial stainless steel interior, which has been tested to have a 99.9% antibacterial rate against E. coli and Staphylococcus aureus. This material is resistant to acid and alkaline corrosion, making it less likely to retain tea stains or odors, making it suitable for various beverages such as tea, coffee, juice, and carbonated drinks. The cup body has a multi-layer temperature-locking design, including an inner layer, a copper-plated isolation layer, a high vacuum insulation layer, and an outer shell, effectively preventing heat transfer and convection to maintain temperature.

The flask lid features a two-in-one design, providing both a direct drinking spout and a removable straw opening, allowing users to switch according to their beverage type or drinking preference. The straw uses a “pop-up straw” design that can be removed for cleaning and automatically pops up when the lid is opened. The screw-on cap can hide the straw opening to prevent dust. The lid is equipped with a locking mechanism that allows for one-handed opening and closing, ensuring a 360-degree seal that prevents leaks, even when turned upside down.

The cup has a capacity of 900ml, and the wide mouth makes it easy to clean by hand or to add ice cubes directly. The outer shell features a skin-friendly paint finish, providing a delicate feel that does not easily attract fingerprints. The entire cup can be fully disassembled for cleaning, eliminating hard-to-reach areas. This product is suitable for daily commuting, office use, outdoor activities, and car use, meeting the needs for both hot and cold beverages, while the two-in-one lid design balances convenience and hygiene.
