SD Toyz My First Impression Kit is the perfect way to pay tribute to your baby while capturing their impression in this precious keepsake. Mold our lightweight, easy-to-use clay into the ideal imprint shape with the shaping ring and rolling tool. Imbed a 2 inch by 2 inch image of your baby on one side, and press their hand or foot into the other. Let the clay air dry for about 48 hours, and then use the colorful ribbon to display prominently. Repeat this process every year to track your babies growth and change. An affordable, must-have for all parents.
