Never hot or cold, sticky or 'icky', the MouseRug's surface is made of millions of individual soft nylon microfibers with air space between to provide the most beautiful and comfortable mousing surface on the planet. 25.5cm x 18cm. One of the most detailed, engaging classic Persian carpet patterns we have reproduced as a MouseRug--in deep, rich colors. This pattern is inspired by a Persian Mahi Tabriz rug design. It uses a very fine example of the curvilinear Herati pattern in its execution.
