A playful way to discover colours and light ... These brightly coloured acrylic cylinders offer children exciting opportunities for creative building, sorting and experimenting. When placed on a light bucket, the translucent colours create a fascinating play of light that visually appeals to children and promotes their sensory perception. The acrylic cylinders can be arranged by colour and size, stacked into towers or laid in patterns, helping children develop a sense of colour gradation, shape and spatial thinking. This versatile material promotes fine motor skills, concentration and the ability to design and combine independently. Ideal for exploring and discovering!
