This is undoubtedly the warmest Christmas card of the season! Each Christmas card comes with a color-changing sticker and an envelope. Crafted from thick, tactile cardstock, adorned with elegant gold foil designs. Write your message and cover it with the heat-sensitive sticker to conceal it. Finally, reveal the message using the warmth of your hands! The reveal effect can be used repeatedly. Available in four designs. Please specify your choice when ordering: A) Christmas Tree B) Christmas Deer C) Christmas Stick D) Christmas Bobo Instructions: After writing your message with a fine red pen, cover the words with the included color-changing sticker. Note: The sticker changes color at approximately 32°C (90°F). Extreme ambient temperatures, either too high or too low, may affect the color-changing effect. (If the outdoor temperature is too low, you can also use a hand warmer or a match to reveal the hidden message.) Note: Different pen thicknesses or colors may affect the sticker's ability to conceal the message. Please be mindful of this.
