A set of 6 Mystery Sensory Balls are reflective mirror balls that look identical but all have individual characteristics.
Some wobble when rolled, or turn and wont roll in a straight line, some feel funny when twisted, spun or shaken, and others make different shaker or rattle sounds.
The shiny mirror surface provides a distorted reflection which is fascinating for children to observe.
They are robustly constructed from hard wearing stainless steel, are lightweight, smooth and tactile to handle.
10cm in diameter.
