The product is themed around a cloth bag, simulating the process of “tying” on the cloth bag. In this game, children learn how to tie knots, fasten buttons, and zip zippers, while also developing arm muscles and improving their concentration and spatial orientation.

Children learn and observe how the teacher ties knots on the cloth bag, and after learning, they practice tying knots, fastening buttons, zipping zippers, and buttoning buttons themselves.
