750ml Insulated Stainless Steel Tumbler with Leakproof Straw

Frequently Asked Questions

Q: What is the capacity of this tumbler, and what are its approximate dimensions?
A: The tumbler has a capacity of 750ml (about 25.36 oz). It is designed to fit most standard cup holders and backpack side pockets. Exact dimensions may vary slightly by batch, but the typical height is around 9 inches and diameter about 3 inches.

Q: How long does the double wall stainless steel insulation keep drinks hot or cold?
A: The vacuum insulation helps keep cold drinks cold for up to 24 hours and hot drinks hot for up to 12 hours, depending on the initial temperature and ambient conditions. The double wall construction also prevents condensation on the exterior.

Q: Is the tumbler truly leakproof, and can it be used with carbonated beverages?
A: Yes, the tumbler features a leakproof straw lid that prevents spills when closed. However, for carbonated beverages, we recommend using the tumbler with caution and not overfilling, as pressure can build up. The lid is designed to seal securely but may not be completely airtight for carbonation.

Q: What materials are used, and is it safe for daily use?
A: The tumbler is made from high-quality 18/8 stainless steel, which is BPA-free, non-toxic, and sweat-resistant. The lid and straw are made from food-grade polypropylene and silicone, both free of harmful chemicals. It is safe for hot and cold beverages and is also rust-resistant.

Q: Can I customize this product with my own logo or design for wholesale orders?
A: Yes, this product supports customization for wholesale buyers. You can have your logo or design printed on the tumbler using methods like screen printing, laser engraving, or pad printing. Minimum order quantities and lead times apply. Please contact our sales team for details.

Q: Is this tumbler suitable for both hot and cold drinks, and can I put it in the dishwasher?
A: The tumbler is designed for both hot and cold beverages, thanks to the double wall insulation. However, for best longevity, we recommend hand washing with mild soap and water. The vacuum insulation may be damaged in a dishwasher. The lid and straw are dishwasher safe on the top rack.

Q: What is the warranty and return policy for this product?
A: We offer a 30-day return policy for unused and undamaged items. Wholesale orders may have different terms. The tumbler comes with a 1-year limited warranty against manufacturing defects, excluding accidental damage or normal wear. Please refer to the warranty card included in the package or contact our support team.

Usage Instructions

• Before first use, wash the tumbler, lid, and straw with warm soapy water and rinse thoroughly.
• Fill with hot or cold beverages as desired. The double wall insulation maintains temperature for hours.
• For hot drinks, preheat the tumbler with hot water for 1 minute to maximize heat retention.
• For cold drinks, pre-chill by adding ice or cold water for a few minutes.
• Close the lid securely to ensure leakproof performance.
• Use the built-in straw for sipping or drink directly from the wide mouth opening.

Precautions

• Do not microwave the tumbler or place it in the freezer as it may damage the vacuum seal.
• Avoid using abrasive cleaners or steel wool that can scratch the surface.
• Hand washing recommended to preserve the 3D print and spray paint finish. The lid and straw are dishwasher safe on the top rack only.
• Do not overfill with carbonated beverages to prevent pressure buildup and leakage.
• Keep out of reach of children when filled with hot liquids.
• Do not use for prolonged storage of acidic or salty liquids (e.g., fruit juice, sports drinks) to minimize potential corrosion.
