Custom Kids 420ml Stainless Steel Vacuum Flask Water Bottle

Frequently Asked Questions

Q: What material is this water bottle made of, and is it safe for children?

A: This water bottle is made from premium 316 stainless steel, which is food-grade, BPA-free, and more corrosion-resistant than 304 stainless steel. It is completely safe for children to use daily and meets international safety standards.

Q: How long does the thermal insulation keep drinks hot or cold?

A: The vacuum insulation technology effectively maintains beverage temperatures: hot drinks stay warm for approximately 6-8 hours, and cold drinks remain chilled for up to 12 hours. Actual performance may vary based on ambient temperature and liquid quantity.

Q: Can I customize this water bottle with my child's name or a specific cartoon design?

A: Yes, this product supports customization. You can add your child's name, initials, or choose from a variety of cartoon patterns. Please contact our customer service team with your design preferences before placing the order, and we will confirm the details and any additional costs.

Q: Is this bottle leak-proof and suitable for school bags?

A: Yes, the bottle features a leak-proof screw cap with a silicone seal, preventing any spills even when placed sideways in a backpack. It is designed to be child-friendly and easy for kids to open and close securely.

Q: What is the exact capacity and size of this flask?

A: The bottle has a capacity of 420ml (approximately 14.2 oz). Its compact size (around 7 cm diameter x 20 cm height) fits most standard cup holders and school bag side pockets, making it convenient for children to carry.

Q: How should I clean and maintain this stainless steel vacuum flask?

A: Hand wash with mild soap and warm water using a soft sponge. Avoid abrasive cleaners, bleach, or dishwasher use, as they may damage the coating or vacuum seal. Rinse thoroughly and air dry with the cap off. For stubborn stains, a baking soda paste works well.

Q: Do you offer a warranty, and what is the return policy?

A: We provide a 1-year warranty against manufacturing defects (e.g., vacuum failure, lid cracks). If you encounter any quality issues, please contact us for a free replacement or refund. Returns are accepted within 30 days of delivery, provided the item is unused and in original packaging.

Usage Instructions

• Before first use, wash the bottle and lid thoroughly with warm soapy water and rinse well.
• Preheat or pre-chill the bottle by filling with hot/cold water for a few minutes before adding your beverage.

Safety Precautions

• Keep out of reach of small children when containing hot liquids to avoid burns.
