This item is a a beautiful Fenton hobnail milk glass bottle for your vanity. The jar itself is in the Hobnail pattern with a long neck and pointed stopper. It is marked with the #4 on the bottom. It measures 8 1/2" high and 3 1/2" across. The neck measures 4 3/4" long.
It is in very good shape. It is unmarked but I believe it to be a Fenton. I'm not sure the original use of this jar but I have used it as a trinket box. Please ask any questions before purchasing.
