With this craft kit, you can make 4 cheerful underwater erasers! Create a fish, octopus, or seahorse using the mold. Happy with your design? Before you can use the clay as an eraser, you need to bake it in the oven. Once the figure is baked, you can use it as an eraser. Twice the fun! Each bag contains 25 grams of clay. The clay comes in pastel colors: pink, green, blue, and orange. It is gluten- and toxin-free. Instructions are included.
