First, I’ll pour in some hot water, then I’ll explain it to you step by step~ Color-changing cups consist of two parts: an outer cup and an inner cup. The outer cup is made of heat-sensitive material, while the inner cup features a premium Grade A coating, so you can drink from it with confidence~ All cups have passed quality certification. The ceramic color-changing mug changes color at temperatures above 45°C. The glass color-changing mug changes color at temperatures below 18°C. If you’d like to learn more about color-changing mugs, Yongrui has specialized in the R&D and manufacturing of these products for 20 years and has extensive experience. If you need to customize various logos, please feel free to contact our professionals.
