Finely detailed, three antique flying geese thread winders.  They appear hand carved from mother of pearl, each slightly different, if you notice very closely.  Beautiful  creamy iridescent color.  Cross hatching on the body with cuts on the wings to simulate feathers.

These little gems are 1-5/8" in length  x 3/4" wide.  Thickness is 3/8" thick.   Again, this size varies slightly. 

A wonderful addition to a sewing collection.
