What our experts think

It was fantastic to witness our testers create 3D block designs and then use their objects to calm their minds, occupy their hands, and express their creative thinking. The children could easily start with simple builds creating their own fun fidgets or figures. This quickly elevated to learning to create more complex and imaginative items that they included in pretend play with peers and family.

Lock Blox sparks innovation and encourages open-ended, repeat play. It can be utilized as a self-regulation tool while also promoting fine motor development, visual perceptual skills, and imaginative play. Lock Blox was not only fun for the kids, but became something the whole family enjoyed.
