The day I received the section pliers I replaced the ink sacs in four Esterbrook fountain pens. After watching how to videos online and reading books and articles that addressed fountain pen repairs I decided I wanted to order the necessary tools and parts and try my hand at repairing my own pens. The section pliers were my first tool purchase and they worked beautifully. I will be ordering tools and replacement parts to begin restoring the more than 50 antique fountain pens I purchased over the last 10 years. As a child, my grandfather taught me to write using his Parker 51 fountain pen in the mid 1950s. I have seven grandchildren and three great-grandchildren, and I plan on repairing a fountain pen for each of them. I only hope they will love and appreciate the beautiful antique pens I will give them.
