This Staedtler FIMO Effect Modelling Clay Block is an oven-hardening polymer modelling clay that is ideal for adult beginners and amateur artists who enjoy model-making in their spare time. It’s soft and pliable, making it easy to shape and mix with other colours to create patterns, gradients, and new colours. The FIMO effect is the product of choice when it comes to creating very special effects as it can be used to give your artwork a whole new dimension. With stunning colours and lifelike reproductions of classy materials and finishes, the clay can make objects shine, shimmer and sparkle, or even glow in the dark.
