From the makers of SuperTech, Kirkland, Amazon Basics and others, there are Warren's Corporate products we normally don't see in stores. I myself had never seen or heard any of their products until I read this catalog/article below. Their products looks like they're sold in Dollar Stores. Nothing fancy.
