THIS IS A PENDANT TYPE PENCIL USUALLY WORN AROUND THE NECK.
Please look at the photos and ask questions.
There is a top ring for adding a necklace.
I don't have a case but it does rest in a padded pencil box.
There is a small dent at the "Sterling" mark but this in no way affects performance or screwing & unscrewing the cap.
Lead advances by turning the dark blue/black barrel piece against the Sterling Silver upper shaft.
Thank you for looking
