This fidget toy has 27 colorful plastic blocks that are connected by elastic. Each cube has slits cut out so you can twist and turn the cubes, putting the elastic rope in the groves to change the direction of the cubes. Kids can create all kinds of shapes with just a few twists and turns! It is fun to have someone make a shape, and have another person use a second fidget to recreate it! Great for children who fidget to self-calm or need a portable activity to keep them focused. The fidget is 14″ long when made into a straight line. Each of the 27 blocks are .5″. This fidget is perfect for travel in car or plane because it is just one piece!
