Nature's Spirit standard dyed herl is easy to work with, 6 to 8 inches in length. Package contains 1/8 oz. NOTE: Because the herl is not bleached before dying, the dominant color in most dyed herl is the natural pearlescent green. The distribution and depth of dyed color varies within each package and the dye color can be very subtle. This is especially true of dye colors that are close to the original pigments, such as yellow, olive, and green.
