Brain Flakes from VIAHART is a new construction toy which teaches children spatial thinking and lets their imaginations run wild! Every jar contains over 500 discs, which means hours of endless fun and engineering education. The discs measure 1.3' across and are 1/10th' thick. They click together and apart easily for all ages and levels of motor skills. They come in a great reusable plastic jar (PET). The discs themselves are made from safe and tested polyethylene (PE). The cap of the jar is made from polypropylene (PP). It's a revolutionary addition to the world of children's (and adults'!) construction toys. Get your Brain Flakes today!
