Vintage Black Metal Soap Dish Holder - unfortunately I don't have the soap dish that would have set into this holder.  It measures 4 1/4" by 3 3/8" and the inside measurement is 2 1/2" by 3 5/8" at the top and 2 1/4" by 3 7/16" at the bottom.  It is in good condition and shows sign of use.  See pictures for best assessment of condition.  Please ask questions!
