If you’re a mom who is sick of throwing away crusty bits of playdough you find on the floor under your table, then this is a step up for you. And it never dries out.

Great product, hours of play (minimum 30 minutes daily) for my 2.5 and almost 5 year old that are now home due to the school closures. It’s a lovely true purple, easily moldable and with a tug will stretch off and fall apart.
