Tactile Chess Set (Magnetic)

While this was designed to be accessible for the blind/low vision, it has benefits for the able-bodied as well. The tactile differences mean that it can be played in the dark and could be a great way to pass a power outage. The magnets keep the pieces where they're supposed to be despite kids, pets, earthquakes, car rides, clumsiness, etc.
