"Great tool when you're nervous, for the kids when bored or just dysregulated in general. Multiple ways to use, scratch, oush together and shake, move marble, rub fabric. It doesn't smell, which i find is so often when you buy something online, it is discreet and comes in colourful but also discreet colours. Love love love it Julia M May 2024"
