Is this paper fountain pen friendly? 
I've tested with my own inks and pens and there is no bleeding or feathering. There is minimal ghosting except with extremely dark/heavy inks that may bleed through.

Will A5 Slim fit my Traveler’s Journal?
Yes, A5 Slim is the same as Traveler’s standard sized notebook inserts.
