A refill insert is the practical part of a refillable leather journal. This one is closest to a slim A5 dot-grid booklet for notes, bullet journaling, sketches, and pen testing.
Quick verdict
The Moonster Dot Grid Refill is better than it looks at first glance. It is a simple kraft-covered insert with thin 70gsm paper, but the writing test is surprisingly positive: pencil, ballpoint, gel pens, and even the fountain pens used in the review behaved well. There is ghosting, because the paper is thin, but the important part is that the fountain pen test did not bleed through.
This Moonster Dot Grid Refill Review is a quick but useful follow-up to the Moonster refillable leather journal review. The leather cover is the permanent part of the system, but the refill is what you actually write in every day. If the insert feels cheap, bleeds badly, or refuses to lie flat, the whole refillable-journal idea becomes less appealing.
The version shown here is the dot-grid refill. It has a plain kraft-style cover, a simple stitched construction, a brown bookmark ribbon, and a page size of about 5.75 by 8.25 inches. That puts it roughly in A5 territory, which makes it a practical size for journaling, bullet journaling, everyday notes, and planning pages.

What you get
The refill itself is intentionally plain. The cover is a cardboard kraft paper cover rather than a decorative notebook cover, and that makes sense because it is designed to sit inside a leather journal cover. You are not buying this refill for a fancy exterior. You are buying it as the replaceable writing block for the Moonster system.
Inside, the paper is white with a dot grid. The dots are useful if you want more structure than blank paper but less visual noise than lined pages. It can work for lists, habit trackers, bullet journal layouts, diagrams, notes, and sketchy planning pages. The dot grid also makes the refill more flexible than the lined insert that comes with some refillable journals.

Size and construction
The stated size in the video is 5.75 inches by 8.25 inches, or about 14.6 by 21 cm. In normal use, that feels close to A5. It is large enough for real journaling but still compact enough to carry inside a leather cover.
The spine is glued into the cover and also stitched. That combination gives it more structure than a loose stack of refill paper. It is still a refill booklet, not a premium hardcover notebook, but the construction looks appropriate for the purpose. Once opened and worked in a little, it lies fairly flat, which matters if you want to write across spreads or use it for longer journal sessions.

Paper feel and dot grid
The paper is 70gsm, so it is not thick, coated, or luxurious. At first glance it looks very ordinary: simple white paper with a light dot pattern. That actually made the writing test more interesting, because the paper performed better than expected.
The dot grid is the main reason to choose this refill over a lined insert. Lined paper is straightforward for journaling, but dot grid gives you more freedom. You can still write neatly in rows, but you can also draw boxes, headers, calendars, trackers, or rough diagrams without fighting a strong ruling pattern.
| Feature | Notes | Verdict |
|---|---|---|
| Size | 5.75 × 8.25 inches, roughly A5 | Practical journal size |
| Paper | 70gsm white dot-grid paper | Thin but usable |
| Cover | Plain kraft-style refill cover | Fine inside leather cover |
| Writing test | Pencil, ballpoint, gel pens, and fountain pens | Better than expected |
| Main weakness | Visible ghosting on the back side | Expected for 70gsm paper |
Writing test
The writing sample is the most important part of this review. The test includes pencil, ballpoint pen, hybrid pens, gel pens, and two fountain pens. The fountain pens are the real test because they show whether the paper can handle wetter ink without feathering or bleeding through.
For a thin 70gsm refill, the result is genuinely good. The page does show through from the other side, but the inks do not punch through in the way you might expect from inexpensive refill paper. That makes the Moonster dot grid refill more usable than its plain look suggests.

Ghosting versus bleed-through
There is definitely ghosting. If you write on one side of the page, you will be able to see some of that writing from the back. That is normal with thinner paper, and it will bother some people more than others. If you only like very opaque paper, this is not going to feel premium.
The more important point is that the test did not show actual fountain pen bleed-through. For journaling, that difference matters. Ghosting means you can see the writing; bleed-through means ink breaks through and can ruin the next page. This refill lands in the acceptable zone: visible ghosting, but surprisingly controlled ink behavior.

Everyday use
As an everyday insert, this refill makes the most sense for people who like the Moonster leather cover and want to keep reusing it. You can fill the dot-grid booklet, remove it, archive it, and put in another refill. That is the whole appeal of a refillable leather journal: the cover ages, but the writing insert keeps changing.
The dot grid is also a good match for mixed-use journaling. If you use one book for notes, lists, planning, reflection, and little layouts, the dot grid gives you more flexibility than the standard lined refill. It is not a luxury paper experience, but it is practical, flexible, and better with pens than expected.

Pros and cons
Pros
- Useful dot-grid layout for journaling, planning, and notes.
- Roughly A5 size gives enough room without making the leather cover bulky.
- Stitched/glued construction feels appropriate for a refill insert.
- Surprisingly good fountain pen result for 70gsm paper.
- Works well if you want to keep using the same leather journal cover.
Cons
- Paper is thin and does show ghosting.
- The cover is plain and utilitarian rather than decorative.
- Not the best choice if you demand thick, premium notebook paper.
- Availability and exact refill type may vary, so check the listing carefully.
Who should buy it?
Buy this refill if you already own, or are planning to buy, a Moonster refillable leather journal and you prefer dot grid paper over lined paper. It is especially useful if you use one notebook for multiple things: journaling, quick notes, bullet-style planning, ink tests, and simple page layouts.
Skip it if you want heavy, bright, ultra-smooth notebook paper. This is a practical refill, not a premium standalone notebook. Its strength is that it makes the Moonster leather cover more flexible and more reusable.
FAQ
Is the Moonster dot grid refill good for fountain pens?
It performed better than expected. The 70gsm paper showed ghosting, but the fountain pens used in the test did not bleed through.
What size is the Moonster dot grid refill?
The refill shown is about 5.75 by 8.25 inches, or roughly 14.6 by 21 cm, which is close to A5.
Does the Moonster refill lie flat?
It lies fairly flat once opened and broken in. It is still a stitched refill booklet, so it does not behave exactly like a heavy hardcover notebook.
Is dot grid better than lined paper?
Dot grid is better if you want flexibility for bullet journaling, boxes, trackers, sketches, and mixed notes. Lined paper is better if you only write straight journal entries.
Final thoughts
The Moonster Dot Grid Refill is a simple product, but it does its job well. The cover is plain, the paper is thin, and the design is very utilitarian, yet the refill is practical and surprisingly capable once you start writing in it.
The standout point is the paper test. I expected more trouble from 70gsm paper, especially with fountain pens, but the result was better than expected. There is ghosting, so this will not satisfy people who want thick opaque pages, but the lack of bleed-through in the test makes it much easier to recommend as a working refill.
If you like the Moonster refillable leather journal system, this dot-grid insert is the refill I would pick for more flexible everyday use.
