These pens were purchased over two years ago and are still writing so that would be a +1 for the Uni-ball Vision Elite BLX .8 mm “bold” rollerball pen.
The Vision Elite BLX is obviously a stick pen, with a tight cap that snaps firmly into place.
The grip is fairly small and made of a hard etched plastic to prevent slippage.
The rollerball does its job providing a smooth no-skip ride against the paper. The ink on the tip is an indication of usage, not ink blobs.
The barrel and tip colors give some indication of the ink color, which is bold but not bright.
The lines are bold and the colors are deep and blackish.
Overall the Uni-ball Vision Elite BLX is serviceable and I will write with them until they dry up, but they are not preferred by this writer. The line is a tad heavy, I did not like the small plastic grip, and pens with caps are just another thing to keep up with. ✍🏾✍🏾✍🏾
