PURPOSE: Accessory made of an unsaturated polyester resin is provided which has a variety of patterns such as embossed surface or matte surface by remaining the trace of abrasive on a desired part of a molded product by sprinkling the small particles of abrasive and consequently improves surface quality. CONSTITUTION: An accessory made of an unsaturated polyester resin is produced by: a first step of molding a thermosetting unsaturated polyester resin into a certain shape and performing abrasion and finishing steps; and a second step of sprinkling abrasive onto the surface of the molded product with a given pressure. The method involves the use of a device characterized by comprising: an abrasive sprinkler body(100) which is supported by a horizontal shaft(200), a vertical shaft(202) and a fixing member(204) which connects the body with the two shafts(200,202); a rubber conveyor belt(206) which conveys molded article(210); a hose(102) for feeding a pressurized air; abrasive which is fed from the hose(102) using the pressurized air; a mask nozzle(106) that passes the abrasive fed form the hose onto the molded article(210), and a roller which conveys the molded article to repeat the whole process in order to form an embossed or matte surface on the article.
