Frequently Asked Questions
Why is SUS316 material recommended for long-term tea brewing?
Tea contains tannins which can cause minor corrosion and permanent staining over time. Medical-grade SUS316 contains molybdenum, making it far superior to 304 in resisting acidity and oxidation. This prevents metallic odors and ensures your tea infuser bottle remains hygienic for years.
How does the tea separation filter work?
The Gencore filter is designed to sit securely at the neck of the bottle. You can place tea leaves in the main body and use the filter to block them while drinking, or place leaves in the filter for controlled steeping. It’s detachable for easy cleaning and leaf disposal.
Is the 380ml or 480ml size better for commuting?
Both are designed to be "car-cup holder friendly." The 380ml (6.6cm diameter) is lighter and fits perfectly in smaller handbag side pockets, while the 480ml (7.0cm diameter) offers more volume for longer journeys or full workdays.
Can Gencore provide the necessary compliance documents for global wholesale?
Yes. All our vacuum flasks are rigorously tested to meet international standards. We provide documentation for FDA, EC, LFGB, and BPA-Free certifications, ensuring compliant market entry for global importers.
