Choosing fountain pen paper & notebooks is really a choice between page flexibility and notebook routine. Some writers want separate sheets and a surface designed around fountain-pen ink behavior; others want a plain journal for regular entries. KOBEHA Graphilo and Yu-sari split along that line, so the useful question is which format and writing traits fit your habits.
Quick verdict
KOBEHA Graphilo is the clearer match if you care about a surface explicitly described as preventing feathering and bleeding. Yu-sari is the more natural fit if smooth texture and quick-drying properties matter more, or if you want fountain-pen and rollerball use in a notebook. Price favors Yu-sari, but the format and ink priorities should lead the decision.

Where each product wins
KOBEHA Graphilo wins for loose-page writing
KOBEHA Graphilo is the better fit for a loose-sheet workflow. The description identifies 50 loose sheets and an unruled setup, making it suitable for writers who want individual pages instead of a notebook. It also has a clear paper-specific angle: a specialized filler is described as creating a uniform surface that prevents feathering and bleeding. That combination makes KOBEHA the more focused choice when ink behavior and page separation matter more than a conventional journal format. The trade-off is the $7.60 higher price, which is easiest to accept when those priorities are central.
Yu-sari wins for notebook-centered writing
Yu-sari is the clearer fit when the writing experience should begin with a notebook. It is presented as an A5 plain notebook and described as all-purpose, giving it a straightforward role for regular notes and journal entries rather than separate loose pages. It is also the lower-priced of the pair, so format and cost point in the same direction. Choose Yu-sari when a notebook routine matters more than KOBEHA's specialized filler description.
Product notes
50 PCS KOBEHA 0100132 Graphilo Fountain Pen Paper A5 8.27x5.83 Inch Unruled

KOBEHA's concrete appeal is the warm-toned page: the description calls it light-cream and the color attribute says Off White. That can suit a softer page appearance, while the named Graphilo Fountain Pen Paper format keeps the intended use clear. The limitation is equally concrete: shoppers who want bright white paper may prefer a different appearance. The title also specifies unruled pages, so anyone who depends on printed line guides should factor that into the decision. At $27.29, it is also the costlier route in this matchup, so its paper-specific presentation should be the reason you choose it-not simply the product name.

Yu-sari earns its case through writing feel and pen flexibility. The description pairs an ultra-smooth texture with quick-drying properties and says the paper complements both fountain pen and rollerball ink. Those are concrete reasons to choose it if you alternate between pen types or prefer a faster-drying page. Its limitation is the listed Red (Orange-Ish) color, which may not suit a neutral stationery palette. The title also says Plain, so the format favors open-ended writing rather than printed prompts or ruling. For a shopper who wants a fountain pen journal with a broader everyday role, Yu-sari keeps the decision straightforward.
Final choice by use case
- Loose-sheet use: choose KOBEHA Graphilo.
- Notebook or journal use: choose Yu-sari.
- Tie-breaker: choose Yu-sari for the lower price, or KOBEHA if its fountain-pen-paper focus is the deciding factor.
