This product is great, great if you enjoy cleaning up or you like multi-coloured floors, clothes, tables, chairs, child etc. If you really don't like someone; BUY THEM A SET, ideal. The colours ended up mixed up within 20 minutes, crumbled everywhere, and I mean EVERYWHERE. Every set should come with a complimentary cleaning kit. The moulds work well, but dust holds together better. You can bake them, but surely this is then 'Game Over', as you'd then need to part with more money to purchase more of the stuff. A couple of reviews mention an unpleasant smell, however I would not recommend sniffing it, just incase some of it crumbles and shoots up your nose, and you die. One set was a present, (I'll get them back someday), the other set, which I flippin' paid for is un-returnable. The marketing team deserve awards for their efforts, how do they sleep at night?
