Children's puzzle with three-dimensional designs, shapes or numbers, by the company Melissa & Doug. It is aimed at young ages and stands out for the handle it has most of the time, helping the child to hold the pieces in their hand. 
Puzzles are an important learning tool for children and at the same time contribute to their development. Through play, they learn to coordinate their hands with their eyes and simultaneously develop fine motor skills. They begin to recognize different shapes, designs, etc., as well as strengthen their perception of space. Finally, they help develop memory and strengthen their self-confidence, as solving the puzzle allows the child to trust their abilities and feel proud to have solved a "problem".
