Review on Betionol 1Lb/16oz White Moldable Plastic Clay: Ideal DIY Modeling Material for Creative Activities & Teaching Kits, Perfect for Adults or Kids by Carol Miller

It says non-toxic and I tested it and found it true. It's polycaprolactone. Polycaprolactone is used in long-term implants in the body. The study "In Vitro Degradation and In Vivo Toxicity of NanoMatrix3D® Polycaprolactone and Poly(Lactic Acid) Nanofiber Scaffolds" published in the Journal of Biomedical Materials Research Part A (2018) concluded that the trademarked polycaprolactone was not tested for toxicity. The product is not intended for medical use, but I'm glad the medical versions of it are perfectly safe. This modeling clay is really as good as claimed. It's fun to use and has so many practical applications too. Good to have on hand. But that's just me. (I received this product in exchange for an honest review and I'm offering that here.)
