Handwritten Warmth Card - Heat-Sensitive Christmas Card (Design C: Christmas Stick)

https://i.imgur.com/OsQz1l4.jpg As the weather turns cold, your Christmas cards need a little warmth too! Discover the sender's message through the heat of your hands. This is undoubtedly the warmest Christmas card of the season! Each card comes with a color-changing sticker and an envelope. Crafted on thick, tactile cardstock with elegant gold foil designs. Write your message and cover it with the heat-sensitive sticker. Then, reveal your message with the warmth of your hands! The reveal effect can be used repeatedly. Choose from four designs: A) Christmas Tree, B) Christmas Deer, C) Christmas Stick, D) Christmas Bobo. Instructions: Write your message with a fine-tipped red pen, then cover it with the included color-changing sticker. Note: The sticker changes color at approximately 32°C. Ambient temperatures that are 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: Pens of different thicknesses or colors may affect the sticker's ability to conceal the message. Please be mindful of this.
