Custom 32oz Stainless Steel Vacuum Flask Water Bottle with Handle

Q: What is the actual capacity of this bottle? The product says both 550ml and 32oz, which are not equal.

A: Our product is available in two capacity options: 550ml (approximately 18.6 oz) and 946ml (32 oz). Please check the listing or select the size you prefer before purchasing. The title includes both for search visibility, but each variant is clearly labeled.

Q: Is the stainless steel used in this flask food-grade and safe for hot beverages?

A: Yes, the flask is made from 18/8 food-grade stainless steel, which is BPA-free, non-toxic, and safe for both hot and cold drinks. It does not retain flavors or rust with proper care.

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

A: This double-wall vacuum insulation keeps hot beverages hot for up to 12 hours and cold drinks cold for up to 24 hours. Actual performance may vary depending on the initial temperature and external conditions.

Q: Can I get a custom logo or design printed on the bottle? What is the minimum order quantity?

A: Yes, we offer custom logo engraving or screen printing. The minimum order quantity for custom designs is 50 units. Please contact our customer service with your design file and quantity for a quote and lead time.

Q: How should I clean this vacuum flask? Is it dishwasher safe?

A: Hand washing is recommended to preserve the vacuum seal and exterior finish. Use warm soapy water and a soft sponge. Do not use abrasive cleaners or bleach. The lid is generally dishwasher safe, but the main body should not be submerged in water or placed in a dishwasher.

Q: What is the warranty on this bottle, and what does it cover?

A: We offer a 1-year warranty against manufacturing defects such as vacuum failure or lid malfunction. It does not cover damage from misuse, dropping, or normal wear. Please keep your order number for warranty claims.

Q: Is the handle securely attached? Can it hold the weight of a full 32oz bottle?

A: The handle is made of durable, reinforced plastic and is securely riveted to the stainless steel body. It is tested to support the full weight of a 32oz (946ml) bottle when filled. However, we recommend carrying by the handle on the side or by the base for extra stability.

Q: How long does shipping take and do you ship internationally?

A: Standard shipping within the United States takes 5-7 business days. International shipping takes 10-20 business days depending on the destination. We ship worldwide, and tracking information is provided for all orders.

Usage:

• Clean the flask before first use. Hand wash with warm soapy water and a soft sponge.
• Pre-heat or pre-cool the flask by filling with hot or cold water for 5 minutes before adding your beverage for optimal insulation performance.
• Close the lid securely to maintain temperature.

Precautions:

• Do not microwave the flask or place it in a freezer.
• Avoid using abrasive cleaners, bleach, or metal scouring pads as they may damage the finish.
• Do not submerge the main body in water; clean the exterior with a damp cloth only.
• The lid is dishwasher safe on the top rack, but hand washing is preferred to prolong the seal's life.
• Keep out of reach of children when filled with hot liquids.
• Do not overfill to prevent leakage when the lid is tightened.
• For hot beverages, allow to cool slightly before closing to avoid pressure buildup.
