There is no perfect finish for everyone. The questions on finish go like this: Is the pen for you, or a special request or to sell?
1. For you and you don't like CA: A. Natural finishes - Waxes and polishes look good but do not last and require frequent cleaning as matter of fact. If one has this kind of habit, it will work well; If not, it will look like it has dirty hand grit after months.
B. Different types finishes, Lacquer, polys, and real long term - Urushi - they all take longer amounts of time with urushi taking roughly a month.
To long term woodworkers, it is often an "insult to our intelligence" to see beautiful wood covered with "shiny". But if we want to sell to the public, we need to "get over it". (See the Russ Fairfield quote below.)
2. Special request: what ever they ask for.
3. General sales: Shine baby shine. Mark Mayo sells and his sales are noted in this link:

While we may "hear" that CA is too plasticy looking, or feeling - that comes from "Pen Makers" but not from the general public, and also from among woodworkers who do love the "feel" of wood. No problem with that, except to recognize where it comes from - woodworkers that like the feel of wood (and I are one!) When selling to the general public, Get outside the "woodworker" mentality and sell to what they want. This is not just Mark Mayo's observations from his sales, but it has been a theme for a long time from pen makers here who sell.
Russ Fairfield wrote this back in 2007:"
The only conclusion that really matters is that of the customer, and I would bet that most of them will go for the higher gloss. People are like crows, they are attracted to shiny stuff."
