Twist-action ballpoint pen. This is the higher-end LEGACY 840 model. The remaining ink in the refill is unknown, so please consider it for testing purposes. It contains a blue ink refill. As a bonus, I'm including a new black ink refill and the original box with a pen case that I had on hand. The pen case is unused, but it has lost its shape. I believe this is from around 1998, the model before the LEGACY 2. Total length: approximately 136mm Barrel diameter: approximately 12mm Weight: approximately 31.2g (including refill) This LEGACY model is not often seen. How about it for those who are looking for one? #penlife #SHEAFFER #LEGACY #legacy #legacy #LEGACY
