The numbers tell you which colours to use to paint each square; result offered for everyone; everyone can paint; the board is already pre-printed and contains a route to guide the activity with colour numbers and borders to be filled in with the corresponding colours. The water-based paints are ready to use and do not require any solvent; the paint bottles can be resealed individually to prevent them from drying out. Each time you change colour, clean the brush with clean water and dry it with absorbent paper; the frame is already included; when you have coloured all the boxes listed with the corresponding colours, let the drawing dry thoroughly.
