Nib: Esterbrook Steel, #2668 (Medium)
Esterbrook No. 407 One of the most popular dip-less sets Esterbrook made. These were often found in banks, post offices and anywhere where a large supply of ink was needed for the general public. Also available with a chain for such purposes.Nib: #2668 (Medium) Dip-Less pens are so called because when used with the corresponding base which holds one to two ounces of ink (depending on model), one could "dip" less than when using an ordinary dip pen. This of course is accomplished through the use of the pen having a feed.
