Could you use Christmas Push 'N Print™ Cutter Set for sculpey clay ornaments?

Would the clay gum up the indents? If you could use it for clay ornaments, it'd sure be a neat perversion of one items use for an other intended use. When I say gum up I mean as far as not pressing cleanly or stickin when you want to pull the cut out of the clay:)
