The description is easily understandable.
The impression material is already done, you have nothing to touch, however, is it is not plaster but a kind of plastic. The finished dried mass remains resilient but do not worry, the actual footprint is not changed thereby.
If you do not roll out the mass too thick, can certainly produce more than 2 footprints.
The mass does not remain on the little fingers and feet stick that's a big advantage but on washing after that I would still not do without. The ground smells very chemical.
This product is thoroughly recommended.
