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. The Emperor's Garden rug inspiring this BookRug is an exquisite example of a type of design known as the Peking style which gained status and popularity during the latter decades of the 19th century. This was a time when China opened its vast workforce, in the form of large weaving factories, to the Western world. A trademark of this style, which reached its zenith of popularity during the 1940s, is its use of pictorial elements, such as pagodas, vases, and realistically drawn flowers, birds and butterflies.
