Colouring by numbers! With the triangular markers, children are encouraged to grip the markers properly. The markers come in 12 bright colours and have a firm point. With these colouring pages, children can colour in the cheerful illustrations number by number. The youngest children are given extra help by the colourful lines around the boxes. This way, colouring is always a party and the 6 colouring pages can be coloured in completely, without any effort.
