Lumin's foam clay starts as a soft, moldable putty, and air dries into a solid EVA foam piece! Perfect for making lightweight but durable cosplay props and embellishments, attaching EVA foam pieces together, filling seam gaps, or for using your imagination with the kids and making a cool creation! Air dried pieces can be sanded, painted and glued. Can be used in silicone molds as well for quick and easy casted pieces. Foam Clay is non-toxic.
