I tried some on a uke I had a few years ago, just to see if they got in the way. They did look like real inlay and gave the markers a cool look (mine were little turtles). They were very thin, so they worked very well. I was concerned with sliding up and down the fret board that I would feel them, or peel them off and they would get in the way and be more of a irritant. I was surprised they weren't. I could feel them every so often, but it wasn't bad, and they were stiff enough where my fingers did not peel them up. I had them on it for a year or two, then removed them. I only removed them because I thought stickers were cheesy, but that is my own OCD issues. It wasn't because they didn't look nice, and real. No one ever noticed that they were stickers until I told them when they mentioned how cute my markers were. They aren't for me really, but wanted to try them out. So, if you don't mind stickers, go for it.
