Playing with Sensory-Sand is a fascinatingly sensual experience. The therapeutic effect of the flowing sand leads to relaxation and deceleration. And offers lots of fun play for people from 3 to 99. The sand has flowing characteristics, but can also be pressed and shaped. Does not stick to surfaces or hands and does not dry out. Sensory-Sand mainly consists of quartz sand and silicone oil. It's all in the mix... Avoid outdoor use and water. If the sand gets wet, just let the sand air dry and the characteristics will return fully.
