Does the Living Clay Expire?

If the package of Living Clay is unopened, the expiration date is typically 2 years, but if it is stored well (cool, dry) it can last longer since it is a dry powder.

To maximize its lifespan, consider storing the clay in a glass jar equipped with a non-metallic lid; when stored under these conditions, it can remain viable for a decade or more. Ensuring the clay is kept in a dry, temperate area within a cabinet and remains uncontaminated will prevent it from expiring.
