Rubikliss Polymer Clay Set is really nice! It comes with 24 colors, sculpting tools, and hardware to make jewelry, key rings, hair accessories, and a button. It definitely compares to Fimo clay in malleability. This clay is really neat in that fact it can be set in 3 different ways. It can be baked, boiled, or you can use a hair dryer to set the clay. I used the traditional method of baking at 266F for 15 minutes per .25”. It baked up perfectly. Due to the potential fumes I did bake these up outside in a small toaster oven. So I cannot comment on fumes indoors.
All in all this polymer clay set is really nice. The clay works well, it comes with everything you need to get started, and it's easy to use. Check it out in the link below:
