Fun with colorful clear colors! This is an educational toy that allows you to visually understand shapes. By removing the small transparent lids, you can put water or sand inside, which also helps in learning about volume. The target age is 8 years old and up, but younger children can also use it for water play in the bath or pool, allowing them to intuitively experience three-dimensional shapes. Of course, you can also enjoy it indoors by shining a light on it! Although unused, there is some minor damage to the box from storage. There are no pets or smokers, but please understand that this is stored by a private individual. - Set contents: 14 pieces - Target age: 8 years old and up - Colors: 6 colors - Accessories: Instruction manual included - Shapes: Three-dimensional shapes (spheres, cubes, cylinders, etc.) Thank you very much.
