Slightly larger than the MIni Fidget series, but still small enough to fit in the hand, the Themed Fidget series is designed to suit the often very strong interests of people on the autism spectrum by theming everything on that fidget around a particular theme. It has been designed with autism and ADHD in mind and packs as much movement and texture into the least amount of space. There are no separating parts, so no choking risk. This version is shaped like a rocket and has seven sections, with a moon, Saturn, sun, star, UFO and rocket engine shaped pieces that can freely rotate. Great fidget to keep fingers busy and minds free.
