Use with the Kumihimo plates to make intricate braids - or whatever else you might want to keep your thread untangled for. The larger curvy side can be folded down over the thread on the bobbin to keep it clean and tidy. These have a loop so you could hang them on a hook. Store other threads, fibres, silk, on these too - not just for Kumihimo!
