FAQ
Q: What material is the flask made of and is it safe for drinking?
A: The flask is made from premium 304 stainless steel, which is food-grade, non-toxic, and lead-free. The inner wall is electro-polished to prevent rust and maintain purity of taste. The exterior is coated with a durable silicone sleeve for grip and protection. This combination is safe for both hot and cold beverages.
Q: How long can the vacuum flask keep drinks hot or cold?
A: Thanks to the double-wall vacuum insulation technology, the flask can keep hot drinks hot (above 60°C / 140°F) for up to 12 hours and cold drinks cold (below 10°C / 50°F) for up to 24 hours. Actual performance may vary based on the initial temperature, ambient conditions, and how often the cap is opened.
Q: Can I customize the bottle with my own logo or design?
A: Yes, this product is designed for customization. We offer various options including laser engraving, screen printing, pad printing, and full-color sublimation. You can personalize the stainless steel body or the silicone sleeve with your brand logo, text, or artwork. Please contact us for artwork specifications, minimum order quantities, and lead times.
Q: Is the silicone sleeve removable? How do I clean the bottle?
A: Yes, the silicone sleeve is removable for easy cleaning. To clean the bottle, wash the stainless steel interior with warm soapy water and a soft brush; avoid abrasive cleaners. The silicone sleeve can be hand washed with mild detergent and air dried. The bottle is also top-rack dishwasher safe, but we recommend hand washing to preserve the customization and sleeve longevity.
Q: What sizes and capacities are available?
A: Our TO-GO vacuum flask is available in multiple sizes: 350 ml (12 oz), 500 ml (17 oz), 750 ml (25 oz), and 1000 ml (34 oz). The silicone sleeve is sized to fit each capacity snugly. Custom sizes can be discussed for large orders. Please check our product listing for exact dimensions and weight of each variant.
Q: Is the bottle leak-proof? Can I use it for carbonated beverages?
A: The bottle features a screw-on cap with a silicone sealing ring, making it leak-proof when properly closed. However, we do not recommend storing carbonated beverages because pressure buildup may cause leakage or difficulty opening. The bottle is ideal for water, coffee, tea, juice, and other non-carbonated drinks.
Q: What is the minimum order quantity (MOQ) for custom orders?
A: For standard customizations (e.g., logo printing on the sleeve or body), the MOQ is typically 100 pieces per design and size. For simpler customizations like laser engraving, the MOQ may be lower at 50 pieces. We offer competitive pricing for bulk orders. Please inquire for exact MOQ based on your customization type and quantity.
Q: What warranty and return policy do you offer?
A: We provide a 12-month warranty against manufacturing defects, including vacuum insulation failure, cap threading issues, and sleeve detachment. If you receive a damaged or defective item, we offer a free replacement or full refund within 30 days of delivery. Customized items are not returnable unless there is a production error on our part. Please refer to our terms and conditions for complete details.
