350/500ml Stainless Steel Vacuum Mug with 2-in-1 Straw

Frequently Asked Questions

Q: What materials is the mug made of?

A: The mug is constructed from high-quality 304 stainless steel with double-wall vacuum insulation. It is BPA-free, food-safe, and designed to maintain beverage temperature for hours.

Q: How long does it keep drinks hot or cold?

A: Depending on external conditions, the 350ml or 500ml mug keeps hot beverages at a comfortable drinking temperature for approximately 6-8 hours and cold drinks chilled for up to 12 hours. Pre-heating or pre-cooling the mug can extend performance.

Q: What does '2 in 1 straw' mean?

A: The lid features two drinking modes: you can sip directly from the spout for a classic coffee mug experience, or insert the included straw through the dedicated opening for easy sipping without tilting. The straw is reusable and fits snugly to prevent spills.

Q: Can I customize the mug with my own logo or design?

A: Yes, the mug is fully customizable. We offer options for laser engraving, screen printing, or full-color wrap printing. Please contact us for minimum order quantities, artwork specifications, and pricing for custom orders.

Q: Which size should I choose - 350ml or 500ml?

A: The 350ml (approx. 12 oz) is ideal for a standard coffee or tea serving, fitting most cup holders. The 500ml (approx. 17 oz) is better for larger drinks, longer commutes, or all-day hydration. Both sizes have the same insulation performance and customization options.

Q: Is the mug dishwasher safe?

A: To preserve the custom print and vacuum insulation, we recommend hand washing with mild soap and a soft sponge. The lid and straw are top-rack dishwasher safe, but the stainless steel body should be rinsed and dried promptly to avoid water spots.

Q: What is the warranty on this mug?

A: We offer a 1-year warranty against manufacturing defects, including leaks or vacuum failure. Normal wear and tear, scratches, or damage from misuse are not covered. Please retain your order confirmation for warranty claims.

Q: Do you ship internationally?

A: Yes, we ship to most countries worldwide. Shipping costs and delivery times vary by destination. Standard shipping typically takes 7-14 business days, while express options can deliver in 3-5 business days. Customs fees may apply depending on your country's regulations.

Usage Instructions

• Before first use, wash the mug, lid, and straw with warm soapy water and rinse thoroughly.
• For maximum thermal performance, pre-heat the mug with hot water (for hot drinks) or pre-cool it with ice water (for cold drinks) for 5 minutes before filling.
• To use the straw: lift the straw opening flap, insert the straw, and sip. To drink from the spout: tilt the mug and sip directly.
• Always close the lid securely to prevent leaks and maintain temperature.

Precautions

• Do not microwave the mug or lid. The stainless steel body is not microwave-safe.
• Do not freeze the mug full of liquid as expansion may cause damage.
• Avoid dropping or subjecting to strong impacts to maintain vacuum integrity.
• For custom printed mugs, hand wash the body with mild soap and a soft sponge to protect the design. The lid and straw are top-rack dishwasher safe.
• Rinse and dry the stainless steel body promptly after washing to prevent water spots.
• Keep out of reach of young children when filled with hot beverages to avoid burns.
