These work great and are very convenient because they are retractable and there is no cover to remove and keep track of. The ultra fine point is perfect for writing on labels. Writes very smoothly.tempest

Love these for labeling all kinds of things including medicines for easy recognition. Lasts a long time and gives a precise line. I will always have sharpies on hand.
