English Leather Box

I am not sure of the age of this wooden box. The label still has the MEM Company, Inc. logo, which means it is before 1996, because the company was sold. The label is marked as English Leather All Purpose Lotion, 4 ounces, Made in U. S. A. There is no zip code. It measures 5 1/4 x 2 5/8 x 2 5/8 inches. I've had it for many years, but only just realized that the corners are dove-tailed. There is no structural damage, but the finish and label show aging and faint discoloration. There is some minor loss to the label. I need your zip code to calculate the postage.
