Product Detail

1. Q: What is the MOQ for this 550ml creative flask? Can I mix the 4 colors?

A: Our minimum order quantity is 100 pieces. Yes, you can mix all four colors (Yejia white, light sky blue, sports black, purple) within one order. This flexibility allows you to test different color preferences for your promotional gift projects with minimal risk.

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

A: Currently, we offer screen printing for logo customization. This method provides vibrant, durable results suitable for most designs. For other techniques (laser engraving, etc.), please consult our sales team for feasibility.

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

A: Absolutely! The 316 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.

4. Q: What is the benefit of the lockable lid? Is it leak-proof?

A: The lockable lid adds an extra layer of security, preventing the lid from accidentally opening in a bag or during vigorous activity. The pop-up lid is designed with a silicone gasket that ensures 100% leak-proof performance when closed properly. It's ideal for sports, travel, and daily commuting.

5. Q: How much does the flask weigh? Is it truly lightweight?

A: Yes, this flask weighs only 300g, making it exceptionally lightweight and easy to carry. Despite its light weight, it maintains durability thanks to the 316 stainless steel inner and 201 stainless steel outer construction.

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, we recommend placing your order at least 45-60 days before your target date to ensure timely delivery.
