The following is from the Axtell Expressions website:
Latex is a wonderful natural rubber from trees in Malaysia and Brazil. It is shipped over and mixed with liquids that we cast into our molds to create the wonderful elastic flexible expressive skin our puppets have. Taking care of the latex is easy, just treat the surface with Armor All Protectant (available from us or your auto parts store) about once every 3 months to keep the sun and ozone off the latex and prolong it's life.
