TRU RED Highlighters (chisel tip) are to narrow to highlight anything meaningful. Also do not require the assorted pack and as the coloe needed to highlight is not in pack am forced to purchase my regular highlighter.
I haven't been able to use them yet as I could not get them open where I needed to use them. I'm sure they'll do just fine once I do get to use them though.
I still find Sharpies to be better quality but functionally they work okay for the price. I am a little worried about how long they last as well. They seem to be more dry than the usual permanent marker.
