Check the listing for details. 10 pcs .043 inch pencil lead for early Waterman pencils, slightly 1.1mm/.046". Condition: New. Listed at 8.00 USD. Ten .043" Long Leads for Vintage Mechanical pencils The standard mechanical pencil lead size for most of the first half of the 1900s was .046 inches, which was metricized variously as 1.1 mm, 1.15 mm, 1.18 mm, and 1.2 mm. These are all nominal approximations -- the actual size of the leads sold under these designations are still all .046 inches, with only very small variations from brand to brand (the designations aren't a consistent guide in this respect, unfortunately). Early Waterman pencils, however, were made to use slightly smaller lead, .043 inch in diameter. Many have since been bored out to use the .046 inch standard, but if you have an old pencil by Waterman (or any other maker) in which standard leads are too tight, jamming and breaking, these slightly thinner leads may be just what you need. Ten leads per tube, HB grade, each lead 9 cm (3 1/2 inches) long. Payment We are glad to combine shipping charges on multiple purchases, but it is vital that the proper checkout method be used.
