This new type of sand, known as kinetic sand is just like the sand on the beach. With kinetic sand you can make sand castles inside without the mess and without and water. The sand sticks to itself like magic, without sticking to your hands. In the pack you get 100g of sand of any colour of your choice. Take it out of the pack, place it on a hard surface and play. The perfect addition to any bare desk. As a stress reliever or just something to fiddle with whilst you work.
