Dear friends,

have any of you had experience completely removing the shut-off valve from the pen? I know that the valve is glued to the rod. But have any of you had success loosening the glue and removing it—and then, of course, re-gluing it? I'm hoping to get some work done on a Dani eyedropper, and it would be performed best if the valve mechanism could be completely removed from the pen and replaced.

Thanks!
