Here's our first-ever in-the-box Parker 41 set with both the fountain pen and "Liquid Lead" pencil! We thought it was a 51 set, at first. Then we read the imprint on the sac protector. The set is in great shape with only light wear from use. The ink sac remains in excellent working order. You will write a fine line with a little feedback and drag using its steel nib. The pencil still seems to have a little liquid lead in it! This is incredibly cool, considering Parker abandoned making those refills in the 1950s or early '60s. Box included.
