One vintage, original box of Esterbrook ink pen nibs. There are 17 x No. 314 Esterbrook nibs in the box. There are also 5 other assorted, original nibs by other makers. I don't know what metal any of the nibs are made from.
The nibs don't appear to have been used. The box has one damaged side and is comparable with age. Please see photos for overall condition.
Any questions please ask and I'll do my best to answer.
