You probably cant see the pirn, its inside the shuttle and loaded for weaving. These are darker than my first batch of pirns which were blond, i guess the darker looks better with the Jarrah wood shuttle. These come five to a pack, which hold a lot of thread (depending on what you are weaving), and allow you to wind all five at once for a longer sit down weaving session. I use a fine swedish bobbin winder, and a I pad the thin shaft with a wind of paper so the bobbin is held firmly in place. They fit the end feed shuttle beautifully.
