Sale!
Clearance Clay Disclaimer: These clays are on sale for a reason: they may not be usable in their current state, and they would require some TLC to get them back to a workable state.
That being said, don't worry! It is very easy to rehydrate a bag of clay, all you have to do is add water in the bag and let it sit for a few days, checking its softness periodically.
All clearance sales are final.
