Culpitt Innovative Sugarworks Sugar Shapers Cake Decorating Unique Tools (Pack of 6), Soft Tip, Mini

Can you use these for polymer clay, or could the clay melt the tools, since polymer clay reacts to some plastics weirdly?

Which size would you recommend for figurine modeling? also, soft or firm? i currently have the pme mini plastic set.

What's the approx. dimensions of each piece?

What exactly are they made of? Is it plastic or silicone?
