The Preston ballpoint takes Parker style refills.
Dimensions can be custom, but standard offerings are
Small are 5″ long, ~ .500″ Ø.
Large are 6″ long, ~.600″ Ø.
Rings are an option, as are the ring materials. Ballpoint clickers are nickel plate only as that’s my only option. Can be had with or without a clip, and custom clips are an option.
Price varies based on materials and any custom options, but starts at $100.
Small size, no ring, standard small size clip.
Small size with custom clip (with a few years use by me).
Large Size pen (top) and pencil (below), standard large size clip. Adding a ring is a custom option.
Shown here taken apart with a spacer between the refill and the button.
Price on the pencil varies based on materials and any custom options, but starts at $135.
Taken apart to show the mechanism that screws into the nose, and the coupler that connects the button. There’s no eraser under the button. A metal button is also a custom option that adds cost to the total. You could also request a custom material for the coupler and button as one piece.
