I've still got my clip from 25 (+!?!) years ago. . .
The clips are still around. The velcro/reflective ones work and they fold up nicely to fit in a back pocket without leaving the impression that you chew tobacco. . .
I keep one wrapped 'round the mini-pump on my down tube because for some reason nobody can design a pump that won't stay put without some sort of "additional" securing device which is velcro and non-reflective (and of course, the shops sell for about double the amount of a set of two or three of the reflective pants strap velcro things.)
The clips are nice because they're quick and easy to take off and put on.
