Frequently Asked Questions

Why is SUS316 stainless steel better for outdoor travel mugs?

SUS316 (medical-grade) contains molybdenum, which offers significantly higher resistance to corrosion and salt-pitting compared to standard 304. For outdoor gear, this means a more durable liner that won't degrade when exposed to acidic beverages or harsh environments, maintaining a fresh taste for years.

Is this 550ml tumbler car-cup holder friendly?

Yes. We have engineered the tapered lower body to fit into 95% of standard vehicle cup holders. With its 9cm top diameter and 18cm height, it provides high volume without sacrificing the convenience of use during daily commutes.

Is the powder-coated finish scratch-resistant for hiking?

Absolutely. Gencore uses an industrial-grade matte powder coating that is baked at high temperatures. This creates a rugged, "No Sweat" exterior that is highly resistant to scratches, peeling, and fingerprints, providing a non-slip grip even when wet.

What certifications do your rugged tumblers provide?

All Gencore products are strictly tested to meet international safety standards. Our 550ml series is fully certified with FDA, EC, LFGB, and BPA-Free standards, ensuring safe market entry for wholesalers in the US and Europe.
