Fimo Effect Modelling Clay is fantastic polymer clay of the most premium quality. This clay is easier to use than ever before. This Fimo Effect Block is ideal for all projects, from simple magnets to intricately designed jewellery to 1:12 scale miniature goodies. The firm smooth texture makes it easier to knead and ideal for mixing colours, yet objects made with Fimo Soft are very durable and strong after baking. For oven-hardening, simply place your modelled item on aluminium foil or a glass plate and let it harden in the oven for a maximum of 30 minutes at a temperature of 110°C/230°F. Your clay design will only be completely hardened when cooled down to room temperature. This product is not suitable for children under 14.
