This is a rare New Old Stock pencil in original packaging that I've had sitting on my desk for too many years. There is some yellowing and corner damage to the packaging, that is probably due to the pencil being moved around in various desk drawers over the last 60+ years. The pencil has a 2mm lead in it. and 

This model is basically the same as the old Koh-in-Noor 5616's that were produced starting in the mid 1950's all the way through the mid 1980's. If you had one of these during that time, chances are you still have it and it is still working just as well as the day you bought it since they were built like tanks.
