Boikido sets the bar high when it comes to quality children's toys that encourage real play time and brain development. This learning center is made with quality eco friendly materials such as FSC wood, and natural water based paints, so you can be confident that your toddler is not exposed to any harmful chemicals. There are no electronic components to this toy, no unnecessary bells and whistles, because it does not need the extras to provide engaging fun for a toddler. The wooden shapes come off of the pegs, to be stacked in order (or not, let them be artistic) over and over again.
