When I had a beard and moustache, I was playing Lee Oskar diatonic harps, and they were fine in terms of "moustache safety "... But I went back to using Hohner diatonics, (which I much prefer), and then I became clean shaven again. Siegfried is quite right about CX-12 chromatic harps, they are fine for 'tache owners...
