That is your opinion and you are entitled to it.
However I disagree strongly I happen to like a shiny finish and ca gives me that while protecting the wood I have worked so hard to make look good behind it.
I am no lover of plastic but I do like a nice smooth and shiny surface on my work and not only pens, I spend a lot of time French polishing things to a piano finish and no i don't think they look plastic.
Why do we have to see your grubby old keyboard when we are supposed to be looking at a pen?
