Any of you use these. I find them extremely hard to get on. Do you think that the stuf that they put on these to make them glow in the dark thickens them. I don't have trouble with other types in this regard. Also, the sensation is reduced quite a bit, which makes me think that they are particularly thick. Also, the glow doesn't last long. I wonder if it could be because I have had them for so long. I don't remember the glow diminishing so fast when I didn't have them for that long.
