Fantastic product, for all ages over 3 I would say, even for antistress. Incredible feel in the hands, nice color and odorless (although there are also scented ones).

It helps to have a surface just for playing with the sand, like a tray, so that the floor or other surfaces don’t get dirty. It doesn’t stain the hands. I keep it in an airtight jar away from moisture, very cold or very hot, I hope it lasts.
