Ensure optimal comfort with our temperature patch, designed for a range of 35~40 degrees. Measuring 16*90mm, it's compact and easy to use. Simply place the patch on the forehead for 15 seconds to reveal the current temperature displayed in green. If the scale shows amber or blue, it indicates body temperature. For accurate results, use at room temperature (21-23°C; 70°F-74°F) and avoid direct sunlight. If the liquid crystal doesn't change color, simply refrigerate (no freezer) for 30 minutes to restore its effectiveness.
