Extra Long THICK Hair Extension FeathersExtra Long grizzly and solid rooster feathers are the most desirable. They are at least 11.5 inches and sometimes longer. For those who want them to stand out, think thick. These feathers should be applied in the top layers of your hair for full impact. Adjust the contrast between feather and hair color to vary the look from dramatic to subtle. XL Thick Long feathers come in packs of 6. They are approximately 1/2 to 1 inch wide and can be washed, dried, and curled. Moonlight Feather, Inc only sells premium feathers from Whiting and Metz.
