Old packs of FIMO some never opened

Many packs of FIMO that are quite old. They’re at least 7 years old and I don’t know enough about the product or whether or not it’s easy to revive. I just don’t have the heart to just throw them away without seeing if there’s someone out there who can use them for something. Hoping there is someone out there who is able to use it. 6 are unopened and the rest are less than 1/4 used each.
