Pack of 20 dried, dyed Forget Me Not flowers.  All pressed flowers do have some fading over time especially with exposure to sunlight.  To keep your flowers the brightest its best to display your piece out of direct sunlight and store your extra flowers in a covered box or a book (somewhere out the sunlight).  The dyed dried flowers will last longer than the natural flowers.
