I tried to flush and test it and it seems to function properly. The vacuum function works great. It could likely using some greasing at some point for the long term functionality. The cap and body has a nice matte/wood grain texture.
The cap has a little bit more wear than the rest of the body. Notably it has some scratches and one or two small dents. They aren't really noticable and can likely be pushed out by a pen smith. Please study the photos, as they are a key part of the description, and feel free to reach out with any questions or concerns. Thank you for checking out my store!
