These are great additions to the multi-pen lineup, been using several for a
while with good results.
Some of the reviewers seem to have issues refilling the lead, using the
"Syringe-style" where you hold down the clicker and carefully load the lead
through the tip. This was how I nerve-wrackingly did it for over a year, until
just a few minutes ago, when I found out that you can gently pull the metal tube
of the barrel away from the the spring/tip component, and drop the leads right
in. I feel a bit the dunce, but better late than never, right?
Also, I use three of these in the same Style-fit 3-pen, to have regular, red,
and blue leads available, and it works wonderfully. Really nice to be able to
consolidate three pencils into one.
These pens draw wonderfully, the price is great, and they are a lot of fun to
work with. However, when I was going back through a sketchbook recently, I found
that the lines I had drawn with the LePens had started discoloring the back
sides of pages, and fading on the fronts. It is a fairly standard sketchbook, in
which I have used any number of other pens and markers with good results, and
the drawings in question were less than three months old. They claim the ink is
acid free, but it was most certainly having some sort of a reaction with this
paper. Perhaps these would be good for quick, just for fun drawings, but I am
now hesitant to use it on anything I mean to archive or sell.
