This type of porcelain is referred to as Elfinware due to its diminutive size, measuring 2 1/2" x 1 3/4" x 2". Often these pieces are call Mossware since they are covered with a green texture and small flowers. It was made in Germany during the 1930's. This one is in very good condition. There appears to be a tiny chip on one of the blue flowers around the opening.
