The same thing happened to me with an Olfa revolving mat. The stench was so strong it made my eyes water to be in the same room with it! None of Olfa's suggestions helped, nor did placing it in my garage in a bag filled with odor-reducing kitty litter for 4 months. It was replaced, and the new one is better, but l still store it out in the garage and only bring it in when I plan to use it right away. Olfa is aware they have a problem with the smell being created during the manufacturing process, but haven't been able to correct it. Too bad, because they have great products.
