These magic doodle cards provide an interactive activity for birthday celebrations. Each card measures 4" x 7 1/4" and includes a 3" plastic writing tool. Children can draw on the cards, and their artwork disappears when lifted, creating a reusable drawing surface. The cards are designed for use as party favors or classroom activities, encouraging creative play. The bright colors and simple format make them accessible for young users. The disappearing ink feature adds an element of surprise to the drawing experience. These cards offer a compact, mess-free alternative to traditional drawing materials.
