What's the difference between ImPRESSive Re-Usable Mold Making Putty MIX and ImPRESSive Re-Usable Putty?

BOTH ARE REUSABLE MOLD MAKING PUTTIES that allow you to

Make molds anytime you want.

The MIX comes as one part

that needs to be heated and kneaded prior to your first use.

The Putty comes already mixed and heated.

That's the only difference.
