These pens can be purchased individually or in sets. I was using the 8-pen set, which includes black, red, blue, green , brown, purple, orange, and rose. The set comes in a plastic case.
The pens can’t really be used as highlighters without risk of bleed-through. The quite easy to see on the page, although I didn’t get a yellow pen to judge against the other brands’ hard-to-see yellow pens. The package say that the ink is an archival ink, which is great in theory—though I won’t be able to report on the accuracy of this claim for 50 years. The 01 (.25 mm nib) is very small, so it feels less clumsy for underlining and writing than the larger-tipped gel pens and the much larger-tipped dry highlighters. It’s a big plus that there is such a range of colors available, so you can choose your own color scheme.
There was no bleed-through, but I could see some of the marks pretty clearly on the reverse side, which was a little distracting on that page. Red was the most visible. I wish there was no show-through, but it’s not to the point of confusing me about which page the mark is on.
Ease of Use
Writes surprisingly smoothly for a non-ball point pen. I’m not sure what the writing tip is made of (anyone know?)—it’s a similar idea to a felt-tip pen, but I don’t think it’s felt. The 8-pen carrying case is a bit unwieldy to be carried around with a Bible. I think the case is meant to be kept in a desk (the pens are intended for illustrators and crafters). The ink smudges a very little bit if brushed against immediately after writing, but much less than the gel ink pens.
