Here is a strange one folks. Inventors contact us all the time to see if we will sell their products. In this case, we said yes. Here is why. The Flat-D (stands for flatulence deodorizer) is a high tech filter that was original designed to defend against chemical warfare. Chemical defense suits were originally made of the material. Well, our fine inventor friend noticed that whenever he passed gas in his chemical suit, you couldn’t smell it. The Flat-D was born. While the packaging isn’t great, the product works very, very well. The company makes a chair pad and an underwear insert. This product is the chair pad. Whether you are buying it for a gag gift or you will put it to great use, the Flat-D’s performance is sure to work. We give a 30 day guarantee that you will be happy with the product.
