Oh dear. I really wanted these to work out! Unfortunately, the ink is WAY too
dark and, while it does erase completely, it smudges my laser-printer book's
print so badly, I can't read the text. I tested it on several printer works and
it's all the same. The color goes away, but the black ink rubs off and smudges
terribly. Can't use these at all. Bummer.
These pens are ULTRA smooth. The pen looks nice and feels good in the hand. They
erase well, especially on good quality paper (magazine paper warps slightly).
The colors are ok, but a bit washed out. I can barely tell the difference
between orange and red, and the black/blue-black/blue pens are VERY subtle
variations. I'm using these pens to write in test-prep books and they work
great, but I can only really assign 6/10 colors to different resources, because
there's no way I'd be able to tell the difference between blue and blue-black or
red and orange notes side by side written in a book. So... I'm addicted enough
that I don't want to wait for a return/reorder, but if I were to do it again,
I'd only order the colors I need and save myself $13.
Oh, and the ink WILL disappear in very hot conditions, but my test sheet (placed
under a hair dryer) came back to near-normal when placed in the freezer. Totally
legible, though a little lighter. That's good enough for me. For archival
purposes, these pens are not a great idea, but this is perfect for my book
annotations, day planner, etc. FYI: friction-erased bits don't come back in the
