The material for accessories (i.e., metal, resin, wood, stone, gypsum, etc.) is dried sufficiently to entirely eliminate any impurities and is put in a cubic box. A vacuum is formed in the interior of the cubic box using a powerful vacuum pump. A spice having a desired fragrance is put in the box and permeates into the pores of the material. The material prepd. by this method emits a fragrance for several months or years according to the quality of the fragrant material used.
