Choosing between fountain pen paper & notebooks comes down to the kind of writing you actually do. The Kokuyo option is a large A4 supply of loose, smooth paper suited to printing, letters, planners, and journals. The A5 Blue Lined Notebook takes the opposite approach: a compact notebook format with ruling already in place. Both are designed for fountain-pen use, so the useful distinction is format and flexibility rather than whether either can handle ink.
Quick verdict
Choose Kokuyo A4 White Fountain Pen Paper when you want blank, loose sheets that can serve several purposes, including office printing and custom planner or journal pages. Choose the A5 Blue Lined Notebook when a blue-covered, ruled notebook is the more natural writing setup. The notebook has the lower listed price, while Kokuyo offers the larger paper supply and A4 format.
At a glance

Where each product wins
- Kokuyo wins for flexible paper use. Its blank A4 sheets can move from office printing to letters, creative projects, custom planners, or journal pages. The acid-free specification and smooth surface also suit shoppers who want a general writing-paper supply rather than a dedicated notebook.
- A5 Blue Lined Notebook wins for structured writing. The horizontal ruling and notebook format give daily notes, lists, and handwriting practice a defined page layout. The blue cover makes the intended notebook format clear, and the lower listed price keeps the choice straightforward for shoppers who do not need loose A4 sheets.
Product notes
Kokuyo A4 White Fountain Pen Paper

Kokuyo makes the stronger case for shoppers who want one paper supply to cover fountain-pen writing and other paper tasks. It is described with minimal feathering, good performance across various nib types and ink saturations, and suitability for double-sided everyday writing. Acid-free paper adds a practical fit for letters, planner inserts, or journal pages that begin as loose sheets. The limitation is the format: it is identified as A4 print copy paper, so it is less directly suited to someone who specifically wants a lined notebook page for daily entries. At USD 27.69, it also sits USD 6.60 above the A5 notebook, a difference that makes sense only when loose-sheet flexibility matters to your routine.
A5 Blue Lined Notebook

The A5 Blue Lined Notebook is the more natural choice when lines should already be set up for writing. Its 0.3-inch (8 mm) horizontal rule and 23 lines per page create a clear structure for notes, lists, and handwriting. The paper is also presented as fountain-pen friendly, with a smooth writing experience and resistance to ink bleeding through the page. Its limitation is the fixed ruled format and 8.3 x 5.8-inch page size: that setup is less adaptable than blank A4 paper for printing or making custom planner pages. Pick it when the blue cover and guided layout are more useful than loose-sheet versatility.
Final choice by use case
- For office printing, custom planners, letters, or journal pages: choose Kokuyo A4 White Fountain Pen Paper. Its A4 blank-paper format, 500-sheet supply, acid-free specification, and stated minimal-feathering performance directly match those uses.
- For lined notes and a dedicated notebook format: choose A5 Blue Lined Notebook. Its blue cover, horizontal ruling, A5 dimensions, and fountain-pen-friendly positioning make the intended writing experience clear.
- For the lower listed price: choose the A5 Blue Lined Notebook, listed at USD 21.09 versus USD 27.69 for Kokuyo. If the price difference is less important than flexible paper use, the Kokuyo ream is the more suitable fit.
