This practical oiler makes oiling the bobbin race easy. Simply pull out the long spout from the bottle, remove the cap and give a squeeze to precisely place a drop of oil in bobbin race area as directed in machine user manual. Replace cap, but do not push spout back into bottle as this could contaminate the oil.
If the oil becomes cloudy or discolored, discard. Handi Quilter recommends oiling every bobbin change.
