It is 100% safe and non-toxic to all. Activa’s new Fast Mache will allow larger craft projects to be completed faster than ever before! Minimal shrinkage makes Fast Mache more versatile in its uses. It has a heavier and tougher finish than the original which enables Fast Mache to be ideally suited for 3-D work and is perfect for all of your school craft project needs. This paper mache works very well with Activa’s Rigid Wrap and Activ-Wire Mesh.
