Custom 32oz Stainless Steel Vacuum Tumbler with 2-in-1 Lid

Q: What is the exact capacity of this tumbler in both ounces and milliliters?
A: The tumbler holds 32 fluid ounces, which is approximately 946 milliliters. This generous capacity is ideal for all-day hydration, whether you are at the office, traveling, or working out.

Q: Is the 2-in-1 lid completely leak-proof when closed?
A: The 2-in-1 lid is designed to be leak-resistant, not fully leak-proof. When the flip-up spout is closed and the straw hole is sealed with the included plug, minor spills may occur if the tumbler is turned upside down or shaken vigorously. For best leak protection, always ensure both openings are securely closed before placing the tumbler in a bag.

Q: Can I put carbonated or acidic beverages into the tumbler?
A: Yes, the 304 stainless steel interior is non-reactive and safe for carbonated or acidic drinks such as soda, fruit juice, or sparkling water. However, we recommend avoiding prolonged storage of carbonated beverages as pressure buildup may cause leakage or difficulty opening the lid. Always release pressure slowly when opening.

Q: What colors are available for the powder-coated exterior, and can I request a custom color?
A: Standard color options for the powder-coated exterior include black, white, navy blue, forest green, and rose gold. Custom colors are available for bulk orders through our customization service. Minimum order quantities may apply. Please contact our sales team for a full color chart and pricing.

Q: How do I prevent condensation on the outside of the tumbler?
A: This tumbler features double-wall vacuum insulation, which prevents condensation on the exterior surface even when filled with ice-cold beverages. The outer wall remains dry and comfortable to hold, making it suitable for use in humid environments or on wooden surfaces without leaving water rings.

Q: Is this tumbler compatible with standard coffee machine drip trays?
A: The tumbler has a height of approximately 8.5 inches (21.6 cm) and a base diameter of 3.2 inches (8.1 cm). Most standard single-serve coffee machines with a removable drip tray can accommodate the tumbler. For larger drip coffee makers, you may need to remove the carafe and place the tumbler directly under the brew basket. We recommend checking the clearance of your specific machine before purchasing.

Q: Do you offer expedited shipping or international delivery?
A: Yes, we offer both expedited shipping and international delivery options. Standard shipping typically takes 7-15 business days within the United States. Expedited shipping (2-5 business days) is available at an additional cost, which will be calculated at checkout. International shipping rates and delivery times vary by destination. Please check our shipping policy page for detailed information.

Usage Instructions

• Before first use, wash the tumbler and lid thoroughly with warm soapy water and rinse well.
• To maximize thermal performance, pre-heat or pre-chill the tumbler by filling with hot or cold water for a few minutes before adding your drink.
• For hot beverages, allow the liquid to cool slightly before closing the lid to avoid pressure buildup.
• Use the flip spout for direct drinking or insert a straw through the straw opening. Ensure the lid is closed tightly when carrying.

Precautions

• Do not microwave or place in freezer – vacuum insulation may be damaged.
• Avoid abrasive cleaners, steel wool, or dishwasher use to preserve the powder-coated finish and lid seals.
• Do not use for carbonated beverages as pressure may cause leakage.
• Keep out of reach of children when filled with hot liquids to prevent burns.
• Do not overfill; leave a small gap for expansion when closing the lid.
• Hand wash only – do not soak for extended periods.
