450 ml Cold-Activated Color-Changing Tumbler

Product Details

• Capacity: 450 ml.
• Cup body: 304 stainless steel.
• Exterior: temperature-reactive color-changing coating.
• Dimensions: 13 cm high, 9 cm top diameter and 6.5 cm base diameter.

How the Effect Works

The effect is cold-activated, not heat-activated. The product specification lists activation at approximately 10–15°C or below. The visible result depends on the temperature of the drink and surroundings; this is not a promise that every part of the coating changes simultaneously.

Care & Use Limits

• Hand wash; do not use a dishwasher.
• Avoid prolonged soaking and high-temperature rinsing of the exterior.
• Protect the coating from scratches, sharp objects and heavy abrasion.
• The lid is splash-resistant, not a sealed leakproof closure.

Hand-Applied Finish

The outer film is hand-applied. Minor edge, texture or surface variations can occur. If your item appears damaged or defective, please contact us with photographs so we can review it under the returns policy.

Questions & Answers
