2-in-1 Insulated Water Bottle & Cooler Can 400ml

Q: What is the material of the water bottle and is it safe for hot and cold drinks?

A: The bottle is made of high-quality food-grade stainless steel with double-wall vacuum insulation. The inner and outer layers are 304 stainless steel, which is BPA-free, rust-resistant, and safe for both hot and cold beverages. It will not leach chemicals into your drinks.

Q: Can this bottle really keep my drinks cold for 24 hours and hot for 12 hours?

A: Yes, the double-wall vacuum insulation technology effectively minimizes heat transfer. For cold drinks with ice, it can maintain low temperatures for up to 24 hours. For hot liquids, it retains heat for up to 12 hours depending on the initial temperature and ambient conditions. Preheating or pre-chilling the bottle before use improves performance.

Q: How does the 2-in-1 design work? Can I use it as both a water bottle and a can cooler?

A: The bottle features a versatile design. The main compartment is a 400ml insulated water bottle with a screw-cap lid for drinking. Additionally, the bottle includes a removable or integrated can cooler section at the bottom (or as a separate attachment) that fits standard 330ml soda/beer cans. You can carry water in the top section and keep a can cold in the lower compartment, or use the entire unit as a standard bottle if you remove the cooler part.

Q: Is the bottle dishwasher safe? How should I clean it?

A: We recommend hand washing the bottle with mild soap and warm water using a soft sponge. The double-wall construction and narrow opening make it unsuitable for dishwashers, as high heat can damage the vacuum seal over time. For stubborn odors or stains, use a mixture of baking soda and vinegar, then rinse thoroughly. Always air dry with the cap off.

Q: What is the diameter of the bottle opening? Can it fit ice cubes?

A: The mouth of the bottle is wide enough to accommodate standard ice cubes. The inner diameter is approximately 5.5 cm (2.2 inches), allowing you to add whole ice cubes from most home ice trays. It also makes cleaning easier.

Q: Do you offer a warranty? What is the return policy?

A: We provide a 1-year manufacturer warranty against defects in materials and workmanship. If your bottle develops a leak or insulation failure within that period, we will replace it free of charge. Returns are accepted within 30 days of purchase for a full refund, provided the item is unused and in original packaging. Shipping costs for returns are covered by the buyer unless the defect is ours.

Q: Can I customize this bottle with my own logo or design?

A: Yes, custom orders are available for bulk purchases (minimum 500 units). We offer laser engraving or silk-screen printing of your logo or design on the stainless steel surface. Please contact our customer service team for a quote and lead time.

Q: Is this bottle leak-proof? Can I carry it in my bag?

A: Yes, the screw-cap lid is designed with a silicone gasket to prevent leaks when closed firmly. It is safe to carry horizontally in your backpack or tote. However, always ensure the cap is tightened properly and avoid overfilling if you plan to tilt or invert the bottle.
