This is an 'uli'uli and an 'uli'uli case. Purchased in Hawaii, the feather parts are real feathers. They are separable. To avoid confusion with others, I have marked the joint of the feather part. The feathers are stored carefully to prevent them from being crushed, so they are still fluffy. I have used them about 5 or 6 times, and they are in very clean condition. Thank you for looking.
