This is a precious sewing box that was made by the German company Reutter. They are hard to find now. This one has discoloration on the bottom from being the tabs that Reutter attached them to the plexiglass cases they use to sell them in.
But other than that it is in great condition. The door opens and closes nicely and the top has a snug fit like it should. 1 1/4" w x 1" deep x 7/8" tall in mahogany wood tone
