I found these boxes of vintage Esterbrook nibs in their original box at an antique shop and absolutely fell in love. The boxes are in great condition, the colors bright and vibrant, the dozen nibs nestled inside like little treasures. The steel is still bright and undamaged and their protective oils have shielded them from any kind of rusting.
Immediately I bought two boxes, picked one out, prepped it in my holder, dipped it in ink and tried writing a few lines. Unfortunately it wasn’t as smooth as I expected, it wrote hesitantly and scratchy, but still not bad for being in the box for over 70 years.
