Q: What is the material of this tumbler and is it safe for hot drinks?

A: The tumbler is made of 304 stainless steel, which is food-grade and safe for both hot and cold beverages. It is free from BPA and other harmful chemicals, ensuring your coffee or tea remains pure in taste.

Q: How does the 360-degree drinking lid work?

A: The 360-degree drinking lid allows you to sip from any side of the rim without needing to rotate the cup. It uses a unique flow control design that releases liquid evenly when you tilt the mug, making it convenient for quick sips while driving or working.

Q: Is this tumbler truly leakproof?

A: Yes, when the lid is properly closed and sealed, the tumbler is leakproof. The lid features a silicone gasket that creates a tight seal. However, please ensure the lid is securely fastened before placing it in a bag.

Q: What is the capacity and does it fit standard car cup holders?

A: The tumbler typically comes in capacities such as 12 oz, 16 oz, or 20 oz. Its tapered design fits most standard car cup holders. Please check the specific product listing for exact dimensions and capacity options.

Q: Can I put this tumbler in the dishwasher?

A: For best longevity, we recommend hand washing the tumbler and lid with mild soap and warm water. The vacuum insulation and outer finish may degrade over time with dishwasher heat cycles. The lid contains silicone parts that are dishwasher safe on the top rack, but hand washing is preferred.

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

A: The double-wall vacuum insulation keeps hot drinks hot for up to 6-8 hours and cold drinks cold for up to 12 hours. Performance may vary based on initial liquid temperature, ambient conditions, and how often the lid is opened.

Q: Do you accept custom logo printing for bulk orders?

A: Yes, the product is listed as 'customized logo acceptable.' For bulk orders, we offer logo engraving or printing on the tumbler. Please contact our sales team with your design and quantity for a quote and lead time.

Q: What is the warranty and shipping policy?

A: We offer a 30-day return policy for defective or incorrect items. Shipping times vary by destination, typically 7-15 business days for international orders. Please check the product page for specific warranty details as some bulk orders may have extended coverage.

Usage

Fill your tumbler with hot or cold beverages. The 360-degree lid allows drinking from any side. To ensure leakproof closure, press the lid firmly until it clicks. For hot liquids, allow a few minutes of cooling before sealing to avoid pressure buildup.

Cleaning

Hand wash with mild soap and warm water. The lid and silicone gasket are top-rack dishwasher safe, but hand washing is recommended to preserve the vacuum insulation and outer finish. Do not use abrasive cleaners or bleach.

Precautions

Do not microwave or place in freezer. Avoid carbonated drinks as pressure may cause leakage. Do not soak in water for extended periods. Keep away from open flames and high heat sources. Children should use with adult supervision when containing hot liquids.

This tumbler is available in the following colors and capacity:

• Capacity: 380ml
• Colors: Beige, Black, Green
