This hand marbled barrette is a symphony of swirling colors.  It has red, yellow, green, blue, purple, and black.  I marbled the colors onto a very lightweight oval wood base that I made and attached to a metal clip measuring 3" (80mm).  The barrette is 3 3/4" x 1 3/4".  It is sprayed with a matte finish to prottect the paint, but you should avoid getting it wet.
