Review on Versatile DIY Tools: 4-Piece Acrylic Solid Clay Roller Set with Clear Acrylic Sheet, Carbon Steel Blades, and Flexible Polymer Clay Cutters for Shaping, Modelling, and Sculpting by Denise Davis

Sorry I didn't read the reviews before buying. I got this for my daughter and I for the audio. I should have looked closely at the picture. The metal parts are razor blades. I just can't, my daughter is 11 years old. I work professionally with my hands. I don't want my 5 year old getting in there. They come in a plastic box. The cut out square is small. What is good. But the protective layer is difficult to peel off. It takes time to detach. We didn't use it on clay after reading the reviews. Maybe it works for others. I threw away the razor blades as soon as I looked at them.
