Product Detail

1. Q: What is the MOQ for this smart temperature flask? Can I mix sizes and colors?

A: Our minimum order quantity is 100 pieces. Yes, you can mix both sizes (300ml and 500ml) and all four colors (black, blue, white, graphite) within one order. This flexibility allows you to test different combinations for your promotional gift projects with minimal risk.

2. Q: How does the smart 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.

3. Q: What is the difference between 'tea strainer' and 'tea separation'?

A: Great question! This flask features both:

Tea strainer (With tea leak) – a removable basket for holding loose tea leaves.

Tea separation function (Tea separation) – the design allows you to separate the brewed tea from the leaves when desired, preventing over-steeping.

Together, they provide the perfect tea-drinking experience.

4. Q: What customization methods are available for this flask?

A: We offer a wide range of customization techniques:

Laser engraving for a premium, permanent mark

Screen printing for vibrant, durable logos

Water transfer printing for full-color, complex designs

3D/5D printing for textured, eye-catching effects

paint transfer and ceramic coating for special finishes

Simply provide your artwork (AI, CDR, PDF), and we'll advise the best method for your design.

5. Q: Is this flask suitable for hot and cold beverages? Does it meet safety standards?

A: Absolutely! The 304 stainless steel inner is food-grade and corrosion-resistant, making it safe for coffee, tea, water, and other beverages. With 6-12 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.

6. Q: What is the weight of this flask? The spec shows 500g for all sizes – is that correct?

A: Yes, both the 300ml and 500ml versions weigh approximately 500g. This is due to the robust construction and smart temperature display mechanism. The weight gives a premium feel, suitable for business gifts where perceived value matters.

7. Q: I need these for corporate events and Business gifts. 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 corporate orders, we recommend placing your order at least 45 days before your event to ensure timely delivery.

8. Q: Do you provide custom packaging for this product?

A: Yes, we offer custom packaging solutions! Standard packaging is one box per flask (One box at a time). We can also provide:

Custom-printed boxes with your branding

Labels, hang tags, and ribbons
