ad 4 I use these as paneling for miniature projects. It's a bit of a bother to disassemble them, but not too difficult. Very appreciative that there's no staples or anything. Can get a lot of material. Cheaper than balsa or other hobby options for the application of thin, real wood pieces. Stains well, good grain (if a bit out of scale at times), and easy to cut and glue. Recommended.
