Vintage mechanical pencil Lead was not sized as metric.  Metric 1.1mm and 1.2mm will not function corerctly in vintage pencils. Fortunately we have acquired a hoard of vintage branded pencil lead still in the vintage containers that fit correctly in vintage mechanical pencils.  The variety is so broad that listing each length, color, hardness and # of leads in each package make it very unweildy to list separtely on this page or to eaily transfer simply to a shopping cart.  The lead shown as ready to be ordered is for the most common  .046"  short medium hardness square leads.  If you need other sizes, colors, hardnesses etc, please use our Contact Us  page so we can make all the options available to you.
