Rollerball pens not only use ink, but also wear the ceramic ball in the tip. American Pen Company's InkBall is refillable with bottled ink, but you may need an extra rollerball tip or two. Depending on individual writing styles, these tips may need to be replaced after 20 to 30 refills of the converter.
Shopping from your home or office need not be a concern. If you decide you’ve made an incorrect choice or the refills you thought you needed were ballpoints (but you actually need a rollerball), no worries. Pens can be returned/exchanged unused for 30 days. Refills are Guaranteed to perform to your standards.
