Beautiful box, Dick,
Some people seem to prefer a satin, butter-soft finish that can be obtained with
a bees wax and turpentine or linseed oil which can be home made

or purchased https://www.bing.com/search?q=bee's+wax+furniture+polish&FORM=QSRE1
and some people prefer a finish such as those shown from the earlier posts with
spray finishes. That could include polyurethane, varathane, shellac, or varnish.
Personally, I like a gloss shine with some of the aerosol products (polyurethane is my preference)
but, some people say that appears more like plastic than solid wood so they prefer a satin finish of the same
products.
I guess I got long winded in saying that different people like a different finish.
I just hope I have given some different choices for people to consider.
Fantastic looking project you have made.
God Bless! Spirithorse
