Labels that change color when exposed to water are generally the size of rice grains and are often affixed to electronic components. When the labels are exposed to water or damp, they will change color and are irreversible. The label bottom paper is made of transparent PET material, which has good toughness, and the label is small but not easy to fall off. The label can be changed to red or blue according to the needs. You can see whether the product has been wet by looking at the label color.
