The Giotto Patplume Modelling Primary Colours Pack contains 6 x 350g bars of vividly coloured modelling clay. The clay is extremely soft, making it very easy to shape and use. Giotto Patplume Modelling Clay allows children to transform their ideas into 3D without the shapes hardening in the air. It is ideal for kindergarten or primary school children. It is clean, odourless and gluten-free, and washes easily from clothes on a 40°C wash. Colours can be mixed together to create a huge spectrum of colours.
