Handwritten Warm Card - Heat-Sensitive Christmas Card (Design A: Christmas Tree)

https://i.imgur.com/OsQz1l4.jpg As the weather grows colder, your Christmas cards need warmth too! Discover the sender's message through the warmth of your hands. This is undoubtedly the warmest Christmas card of the season! Each Christmas card comes with a color-changing sticker and an envelope. Crafted with thick, tactile cardstock and adorned with golden graphic designs. Write your message and cover it with the heat-sensitive sticker to conceal it. Finally, reveal the hidden message using 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: After writing your message with a fine red pen, cover the words with the included color-changing sticker. Note: The sticker's color-changing temperature is around 32°C. Extreme ambient temperatures (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 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.
