Oh, there is one other thing to note. The clip requires filing a little notch in the cap, so that it seats properly. If the notch is not filed, the end of the cap and the clip sit unsightly on the cap. Its not really that hard to do...but it does take a bit of time and a fine file. I didn't read the instructions clearly and missed this the first time, and ended up having to disassemble.
I think Berea also has a snap cap pen. I'm pretty sure its almost the same thing (same finial with the snap lip, and the same insert into the cap that makes the snap functionality work), but...IIRC it looks a bit better, and may not have the requirment of filing for the clip. I haven't tried the Berea one yet, as I decided to start turning higher end rollerball and fountain pen kits. I think the Berea overall may be a better kit than the Artisan one I linked, though.
