Thanks to the colored motif lines, children can quickly recognize the entire design of cute koalas and the colors. The brush provides good guidance, allowing a perfect picture to gradually emerge. The beautiful coloring motifs make a great gift idea for children aged 9 and up and serve as lovely decorations for a child's room. This painting set includes 15 pre-mixed acrylic colors. With Ravensburger's paint by numbers, children learn to color areas carefully, improve their painting talent, and develop fine motor skills. In the end, they experience joy, pride, and a sense of accomplishment that encourages them to continue painting. The motifs are age-appropriate and come in three difficulty levels: from simple images with few, large coloring areas to pictures with many small coloring areas for advanced users. Each painting set contains everything artists need to paint, and there's no need to mix the colors.
