This is a really fun touch game product. Remember that it is very easy to shape. The instructions say to dry the product. What they don't say is that you have to do this after each use. You cannot put it in a sensory container and leave it the next day, otherwise it will become completely moldy, which is unhealthy. It's quite an expensive sensory filler compared to anything I usually use, even water balloons can be reused for weeks without becoming toxic. I just think the company should have a better warning in the instructions and I want teachers and families to be warned not to waste $20 or infect anyone.
