Frequently Asked Questions

Q: What sizes are available for this tumbler cup?

A: This cork bottom double wall stainless steel tumbler cup is available in two sizes: 12 ounces and 20 ounces. The 12oz size is ideal for a standard coffee serving, while the 20oz size accommodates larger beverages or longer outings.

Q: Is the tumbler dishwasher safe?

A: We recommend hand washing the tumbler to preserve the natural cork bottom and the vacuum insulation. The stainless steel body and lid can be rinsed with mild soap and water, but avoid soaking the cork. Dishwasher use may cause the cork to deteriorate or the insulation to weaken over time.

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

A: The double wall vacuum insulation helps keep hot drinks hot for up to 6 hours and cold drinks cold for up to 12 hours, depending on the starting temperature and ambient conditions. The cork bottom also provides a small insulating layer to help maintain temperature.

Q: Is the lid spill-proof or leak-proof?

A: The tumbler comes with a slide lid that helps reduce spills during sipping, but it is not completely leak-proof. The lid has a silicone seal that works well for casual travel, but do not expect it to be fully leak-proof if the cup is turned upside down or shaken vigorously.

Q: What is the cork bottom made of and how do I care for it?

A: The bottom is made of natural cork, which provides a non-slip grip and extra insulation. To care for the cork, keep it dry and avoid prolonged exposure to water. If the cork gets damp, let it air dry completely. Do not scrub the cork with harsh chemicals or place it in a dishwasher.

Q: Can I use this tumbler for carbonated drinks?

A: It is not recommended to use this tumbler for carbonated beverages such as soda or sparkling water. The sealed lid can trap carbon dioxide pressure, which may cause the lid to pop open or lead to leakage. Stick to still drinks like coffee, tea, water, or juice.

Q: Does this cup come with a warranty or return policy?

A: Most sellers offer a standard 30-day return policy for defects or dissatisfaction. While a specific manufacturer warranty may not be listed, any issues with the vacuum seal, stainless steel integrity, or lid function upon receipt are typically covered. Check the listing or contact the seller for exact terms.

Usage & Care Instructions

• Handwashing recommended: Wash the tumbler with mild soap and warm water. Use a soft sponge to avoid scratching. Rinse thoroughly.
• Cork care: Keep the cork bottom dry. If it gets wet, let it air dry completely. Do not submerge or machine wash.
• Preheating/Precooling: For optimal insulation, preheat with hot water or precool with ice water for 1 minute before use.
• Lid use: The slide lid is designed for sipping, not for leak-proof transport. Avoid shaking or turning upside down with liquid inside.
• Avoid carbonated drinks: Pressure buildup may cause the lid to burst. Use only still beverages.
• Do not microwave or freeze: The stainless steel and cork are not microwave safe. Do not freeze as the cork may crack.
