Vintage 144 DUR-O-LITE MARK SENSE Leads, about 0.046\" Thick and 1.375\" Tall. For Sale

Actual shipping costs: I am using the Shipping Tools, so I do not profit from shipping.Vintage one Full Box of 144 DUR-O-LITE MARK SENSE Leads.This sale is not forthe exact box of leads, but for the same item shown in the photos. I have some of these boxes that I sell individually. This listing is only for one full box (has 144 leads).I will surely count each box you purchase to ensure each sold box sold has exactly 144 leads.
Each Lead is About 0.046\" (between 1.1mm and 1.18mm) Thick and 1.375\" (1 3/8\") Tall.Condition: Unknown condition of leads. Leads quality is not guaranteed given the long age of storage. The box is very dirty and has stains, rips, and some imperfections.
Given the rarity of this listing, I will not accept any offers.

• It is very rare to find Mark Sensing Leads that are 1 3/8\" tall. Autopoint Company is probably the only other company that produced Mark Sensing leads in this length (i.e., not included in this listing). It worth to mentionthat the Autopoint\'s version of these leads is called \"Black Dense Mark Sensing\" leads (again, not included in this listing).
• More often, Mark Sensing leads are offered in this1 3/8\"length when they are much thicker, particularlyabout 1.9mm (i.e., not included in this listing). It is also worth to mention that these thicker 1.9mm leads were made by the the Waterbury company and they were called \"Senso-Mark Leads # 200-077 (again, not included in this listing).
• It is much more common to find the 0.046\" thick Marking sensing leads in differentlengths, all taller than 1 3/8\".
