LOVE THIS!  Early home made emery...early fabric, hand stitched.  Very primitive....made to be used to clean the needles!  The red part measures 1 3/4 inches long....with the "handle" is 2 3/4 inches long.  I would date this to the 1920s or 30s....great condition.  If you have some old green fabric, I would add the leaf to the top and then amazing!....please feel free to ask any questions.
