We generally run on a staff of 10 or less, and we all work really hard. All employees here are treated like family...we DO also think of our customers as family, but that does mean if you are "tormenting" one of our "little brothers or sisters", we'll "ground" you. And if you're *really* naughty, you might get a policy named after you. So just be nice, ok? You be nice to us, and we'll do our best for you! That's a promise.

We are not Amazon and don't want to be. We're a bit old-fashioned I guess...but with a website. This is a 40 year old family business, now being run by the second generation. We generally run on a staff of 10 or less, and we all work really hard. All employees here are treated like family...we DO also think of our customers as family, but that does mean if you are "tormenting" one of our "little brothers or sisters", we'll "ground" you. And if you're *really* naughty, you might get a policy named after you. So just be nice, ok? You be nice to us, and we'll do our best for you! That's a promise.

There are lots of great clay suppliers nationwide that probably do a better job of serving customers in states further away. If you would like help finding a local supplier, please let us know. We will be happy to assist you. Please note that we favor long term relationships with our customers over one-time transactions on our website based on a random google search result. We are not Amazon and don't want to be. We're a bit old-fashioned I guess...but with a website. This is a 40 year old family business, now being run by the second generation. We generally run on a staff of 10 or less, and we all work really hard. All employees here are treated like family...we DO also think of our customers as family, but that does mean if you are "tormenting" one of our "little brothers or sisters", we'll "ground" you. And if you're *really* naughty, you might get a policy named after you. So just be nice, ok? You be nice to us, and we'll do our best for you! That's a promise.
