Frequently Asked Questions
Why is 18/8 stainless steel better for a desktop coffee mug?
18/8 (SUS304) stainless steel is a food-grade material that contains 18% chromium and 8% nickel. This combination makes Gencore mugs highly resistant to rust and corrosion while ensuring no "metallic taste" is transferred to your coffee, meeting the highest health standards for daily office use.
Is the Gencore one-touch lid 100% leak-proof for bag storage?
Yes. Our one-touch lid features a high-tension spring mechanism and a medical-grade silicone sealing ring. Once pressed into the "Seal" position, it creates a 360° airtight barrier, ensuring 100% leak-proof performance even when inverted in a backpack.
Does the powder coating peel or scratch easily?
No. We use an advanced high-temperature powder coating process that creates a textured, scratch-resistant finish. This provides a non-slip grip and maintains the mug’s premium aesthetic through hundreds of dishwashing cycles or outdoor adventures.
What certifications do Gencore mugs provide for B2B importers?
We ensure all our drinkware meets global import regulations. Our 18/8 series is fully certified with FDA, EC, LFGB, and BPA-Free standards, providing a safe and compliant supply chain for Amazon sellers and global retailers.
