Custom 316 Stainless Steel Insulated Water Bottle 350-750ml

Frequently Asked Questions

Q: What is the difference between 316 and 304 stainless steel?
A: 316 stainless steel contains molybdenum, making it more resistant to corrosion and pitting from acidic beverages like coffee, tea, or milk. It is also more durable and safer for long-term use. Our bottle uses high-quality 316 stainless steel, exceeding the standard 304 grade.

Q: What sizes are available for this water bottle?
A: We offer three capacities: 350ml, 500ml, and 750ml. The 350ml is ideal for a small coffee or juice, the 500ml fits standard cup holders, and the 750ml is great for all-day hydration or larger drinks. Custom sizes may be available upon request for bulk orders.

Q: Is this bottle truly leakproof?
A: Yes, our bottle features a precision-engineered leakproof seal. The screw-on lid with silicone gasket prevents any liquid from escaping, even when tipped over or shaken. It is safe to toss in your bag without worry.

Q: How long does it keep drinks hot or cold?
A: Thanks to the double-wall vacuum insulation, hot drinks stay hot for up to 12 hours and cold drinks remain cold for up to 24 hours. The 316 stainless steel also helps maintain temperature without transferring heat to the exterior.

Q: Can I put hot liquids like boiling water or milk in this bottle?
A: Absolutely. The 316 stainless steel and vacuum insulation are designed to handle boiling water and hot milk safely. The outer surface stays cool to the touch, and the leakproof lid ensures no spills. Always close the lid securely after filling.

Q: Is this bottle customizable for business or personal use?
A: Yes, we offer customization options such as laser engraving, screen printing, or embossing with your logo, text, or design. Minimum order quantities may apply for customizations. Contact our customer service team for details and pricing.

Q: What is the warranty and shipping policy?
A: We provide a 1-year warranty against manufacturing defects. Free standard shipping is available for orders over a certain amount (varies by region). Expedited shipping can be arranged at checkout. Returns are accepted within 30 days if the item is unused and in original packaging.

Q: How do I clean and maintain the bottle?
A: Hand wash with mild soap and warm water using a soft sponge. Avoid abrasive cleaners and dishwasher use, as high heat may damage the vacuum seal. The wide mouth allows easy cleaning. For milk or coffee, rinse immediately after use to prevent odor buildup.
