Frequently Asked Questions
What is the benefit of 316 vs 304 stainless steel in travel mugs?
SUS316 (medical-grade) contains molybdenum, making it significantly more resistant to corrosion and oxidation than standard 304. It is safer for acidic drinks like coffee, juice, and carbonated beverages, ensuring no metallic taste and a longer product lifespan.
Is the 500ml Commuter Series lid easy to clean?
Absolutely. Effortless hygiene is a core design feature. The entire lid assembly, including the food-grade silicone straw and sealing rings, can be fully disassembled for deep cleaning, preventing mold and residue buildup common in standard bottles.
Does this 17oz vacuum flask fit in car cup holders?
Yes. The base diameter is precisely 7.0cm, which is compatible with 99% of standard vehicle cup holders. Combined with the one-touch opening lid, it is the safest hydration solution for driving.
What certifications do Gencore bottles carry for international wholesale?
All Gencore drinkware products undergo rigorous third-party testing. Our materials are fully certified with FDA, EC, LFGB, and BPA-Free standards, ensuring safe and compliant entry into all major global markets.
