I wish I had read the reviews before I purchased these highlighters. As many have said, the "lead" does not stay out when you try to use them. All 4 of them, same thing. You must hold it almost horizontal to use the side of the "lead" to mark anything and if you accidentally use ANY pressure it retracts. Would have given zero stars if possible.
The older highlighters worked great. For some reason, quality of pen was reduced to this new style. Cheaper plastic and the "lead" slides back into the pen when trying to use--something that didn't happen with the older ones. These are fairly unusable unless one holds them at a very low angle.
