Review on Caydo 9-in-1 Stylus Set - 5 Dual-Purpose Silicone and Ceramic Clay Tools, 4 Metal Ball Tools by Carrie Spencer

I recently bought these in preparation for polymer clay as an art medium. And they are great at that. For the money I've spent, they do what I want: They provide a base for learning how to work with polymer clay. Ball tools are heavy and do their job quite well. However, silicone molds are very thin. In fact, one of the silicone tools broke at the top, although I've never had this happen with any of the others. I really think the silicone should be harder if they are going to be used with polymer clay.
