I didn't know what to expect with this one, but was pleasantly surprised by the different types of things you could do with it. Is totally transparent and is like looking thru glass. It can be formed, molded, twisted, pulled, and pressed. If you read the description, it does everything it says it does and more. It even came in a nice steel storage can to keep it fresh. I will be buying more.
