Off to what Haroun hopes will be the last leg of shopping!
School-supply stores in Elhom IV don't currently offer spiral-bound notebooks, but the notebooks they do have open easily and close easily. Bella can find a nib pen that writes fairly easily, doesn't spill easily, and has infinite ink and self-repair, for three gold. Pencils don't seem to exist yet.
After Bella explains why pencils, Haroun asks somebody at a school supply store to "just write down the incantations" for spells for erasing, highlighting, bookmarking, and, why not, that spell for searching inside notebooks he's been drooling over since forever. Searching inside a notebook would take more mana than Bella currently has, but erasing and highlighting and bookmarking look easy enough.
