Hi Eve, it’s an Italian modelling paste. It smells gorgeous and doesn’t need much kneading. It dries hard enough to keep it’s shape and be sturdy (we didn’t need to use anything to keep the skirt flicked out) but it doesn’t go fully hard for days, so you can take your time working with it and make adjustments. We had portions of it out on our workstations all day without any cover, and you could still squash it up and knead it again hours later. Normal sugarpaste or flowerpaste would be ruined if it was left out!
