One concern I had was that the strings would curl or fray at the edges after long periods of playing. But that doesn't seem to be a problem with block markers. More complex designs may have problems, I don't know. But edges and corners rarely, if ever, touch the strings. And they look good and I don't read any complaints from others. I don't think I would use them on an expensive instrument, but they grace my smaller guitars.
