Frequently Asked Questions
Why is 316L stainless steel essential for a mini pocket cup?
316L is a medical-grade alloy that provides better corrosion resistance than 304, especially against chlorides and acids found in beverages like tea and coffee. In a small, airtight flask, 316L prevents metallic odors and ensures long-term hygiene, which is vital for users who also use it as a mini food jar for soups or baby food.
Will this 8oz mini flask leak if I put it upside down in my purse?
No. Every Gencore pocket flask is engineered with a precision screw-on lid and a 360-degree food-grade silicone sealing ring. It provides a 100% leak-proof seal even when shaken or inverted, making it safe to carry next to your phone and documents.
Can the wide-mouth opening accommodate full-sized ice cubes?
Yes. The "chubby" design features a 5cm wide mouth, which is significantly wider than standard slim bottles. This allows for easy ice filling, fruit slice insertion, and effortless hand-washing, solving the common problem of difficult cleaning in small flasks.
Are Gencore mini flasks safe for sensitive users like toddlers?
Absolutely. Health is our primary concern. All materials, from the 316L steel interior to the BPA-free PP lid and silicone base, are fully certified with FDA, EC, LFGB, and BPA-Free standards, ensuring no toxic chemical leaching.
