Excellent product. I bought them for use in polymer clay sculpting and clay sculpting, but the first thing j used them for was molding apoxie sculpt. In not sure if these were designed for that, but they handled it remarkably well, as long as they are thoroughly cleaned and the two-part apoxie is not allowed to dry. Great for detail work and larger pieces. The various sizes and shapes of the tools allows for creative use, and you can apply the tools in any way you imagine. This is a great product for those just starting out with smaller projects, but I can’t say i recommend this if you are working with solid blocks of real clay, as it lacks the tools needed to separate the clay, but if you are buying it for detail work or for extra tools, it should fulfill most of your basic needs.
