Latest Vintage Find: TEC Drawing Leads

Latest E-bay vintage drafting lead find just arrived: 2 mm TEC drawing leads. Manufactured in the USA in 1960s-70s according to the Leadholder Drafting Museum.

The half gross of leads were packaged in six plastic tubes (12 leads per tube) with threaded metal caps that screwed on securely.
In order to lower production costs: these graphite leads were left blunt on both ends (no pointing), and feature no markings indicating their degree nor brand. I really doubt that they would have saved that much by not sharpening the leads, but this marketing quirk makes them rather unique among my selection of drawing leads. According to the paper insert in each tube each graphite grade corresponded to a given color. For example the 3B leads color code was maroon, yet no evidence of that color coding remains on the leads.
Sample doodle on printer paper: smooth, strong, long wearing point as advertised. If you can find them at prices competitive with modern graphite leads, I would recommend picking them up.
