Frequently Asked Questions

Q: Is the 304 stainless steel safe for hot and cold drinks?
A: Yes, 304 stainless steel is food-grade and non-reactive, making it safe for both hot and cold beverages. It does not leach chemicals or affect taste, and it is resistant to rust and corrosion.

Q: How long does the vacuum insulation keep drinks hot or cold?
A: The double-wall vacuum insulation technology maintains beverage temperature for up to 12 hours for hot drinks and 24 hours for cold drinks when pre-conditioned (preheating with hot water or precooling with ice water). Actual performance may vary based on ambient temperature and usage.

Q: What is the straw made of, and is it BPA-free?
A: The included straw is made from high-quality, food-grade polypropylene (PP) plastic, which is BPA-free and safe for repeated use. It is designed to fit the lid securely and is easy to remove for cleaning.

Q: Can the cup be customized with a logo for promotional giveaways?
A: Yes, this cup is ideal for corporate giveaways and events. We offer customization options including laser engraving or screen printing of logos. Please contact our sales team for minimum order quantities and pricing.

Q: How do I clean the cup and straw properly?
A: Hand wash is recommended. Use warm soapy water and a soft sponge. The straw can be cleaned with a narrow brush (not included). Avoid abrasive cleaners or dishwasher use, as high heat may damage the vacuum seal or straw. Rinse thoroughly and air dry.

Q: What is the warranty on this thermos cup?
A: We offer a 1-year warranty against manufacturing defects such as vacuum failure, leaks, or lid issues. Normal wear and tear, including scratches or dents from drops, is not covered. Contact our customer service for warranty claims.

• Straw Cleaning: Use a narrow brush (not included) to clean the straw interior. Rinse thoroughly.
• Hot Beverages: Exercise caution when drinking hot liquids directly from the straw to avoid burns. Allow to cool slightly if needed.
