Product Detail

1. Q: What is the difference between the 'smart temperature display' and 'basic' versions?

A: The smart temperature display version features a touch-sensitive lid that shows the real-time temperature of the liquid inside (battery-free, powered by body heat or ambient temperature). The basic version has a standard lid without display. Both offer the same 304 stainless steel construction and 12-24h insulation. You can mix both versions in one order.

2. Q: What is the MOQ for this 500ml flask? Can I mix colors and versions?

A: Our minimum order quantity is 100 pieces. Yes, you can mix all four colors (black, red, white, pink) and both versions (smart and basic) within one order. This flexibility allows you to test different combinations for your promotional gift projects with minimal risk.

3. Q: How does the temperature display work? Does it need batteries?

A: The temperature display uses thermochromic technology or a battery-free sensor that reacts to the heat of the liquid. No batteries are required – it's powered by the temperature difference. Simply touch the lid, and the display shows the approximate temperature (e.g., hot/warm/cold indicators). It's safe, durable, and maintenance-free.

4. Q: Is this flask suitable for hot coffee and cold drinks? Does it meet safety standards?

A: Absolutely! The 304 stainless steel inner is food-grade and corrosion-resistant, making it perfect for coffee, tea, water, and other beverages. With 12-24 hours of insulation, it maintains optimal temperature for extended periods. While this product does not come with a pre-existing third-party report, we can arrange FDA or LFGB testing upon request to ensure compliance with international safety standards.

5. Q: I need these for Spring Festival (Chinese New Year) and corporate events. What is your lead time?

A: Our standard production time is 15-20 working days after sample approval, plus shipping. We offer 48-hour rapid sampling to get your project started quickly. For seasonal promotions like Spring Festival, we recommend placing your order at least 45-60 days before your target date to ensure timely delivery.

6. Q: Do you provide custom packaging? What is included?

A: Yes, we offer custom packaging solutions! Each flask comes in a single color gift box as standard. We can also provide:

Custom-printed boxes with your branding

Labels and hang tags

Bulk packaging options

Just share your requirements, and we'll create a complete gift-ready solution for your custom insulated bottle wholesale order.

7. Q: What is the weight of this flask? Is it heavy?

A: This flask weighs approximately 1000g (1kg) , which is typical for a 500ml stainless steel vacuum bottle with smart display features. It's sturdy and premium-feeling, ideal for corporate gifting where perceived value matters.
