Quick verdict: A self-adhesive elastic pen loop is the simplest choice for a hardcover notebook you plan to keep; a removable clip-on holder makes more sense for a borrowed, replaceable or delicate cover. Choose a band-style holder when you want to carry the notebook closed with a pen attached. Match the loop to your pen’s barrel diameter and the thickness of its grip rather than buying only by colour.
This guide compares real attachment styles using manufacturer documentation. It does not claim to have personally tested the holders or their adhesive life.
Quick Comparison
| Holder | Best for | Trade-off |
|---|---|---|
| Leuchtturm1917 standard adhesive loop | Everyday slim pens on hardcover notebooks | Permanent adhesive placement |
| Leuchtturm1917 XL adhesive loop | Wider writing instruments | May feel loose with thin pencils |
| MIDORI clip-style holder | Removable, reusable setup | Clip can mark soft covers |
| MIDORI adjustable pen-holder band | Taking one notebook and pen along | Size compatibility matters |
| Notebook with built-in loop | Zero extra accessories | Fewer notebook choices |
1. Leuchtturm1917 Pen Loop — Best Simple Adhesive Option
Leuchtturm1917’s official specifications list a self-adhesive 1.6-by-1.6-inch backing and a 0.6-inch elastic loop. Its purpose is to attach to a notebook cover so a writing tool stays alongside it. The specified loop width is a useful first check, though fabric elasticity and pen-grip shape influence actual fit.
Buy if: you own a sturdy hardcover planner and use the same slim-to-medium pen every day. Skip if: the notebook is a valuable collectible, you change notebook covers frequently, or the pen is unusually thick. The glue shouldn’t go onto paper that needs to remain pristine.

2. Leuchtturm1917 XL Pen Loop — Best for Thick Barrels
The brand offers an XL model with a 0.8-inch elastic loop and the same 1.6-inch square adhesive base. That’s larger than the ordinary loop and may better suit chunky rollerballs or fountain pens. Do not assume it will hold every thick pen securely; very heavy or smooth metal barrels can slide, especially when the notebook is carried upside down.
Buy if: the standard loop is clearly too tight for your preferred pen. Skip if: a thin mechanical pencil is your everyday tool. A loose holder may be worse than no holder during travel.

3. MIDORI Mini Clip Holder — Best Removable Choice
MIDORI describes its Mini Clip Pen Holder as a stainless-steel clip with a flexible spring that accommodates different pen diameters, including some multi-colour pens. Its listed inner diameter is 7 mm, but the clip’s spring and overall design are what allow it to accommodate some wider instruments.
Buy if: you want to move one holder between notebooks and avoid sticking adhesive to a cover. Skip if: your notebook has a soft, fragile, coated or easily scratched cover. Even a small metal clip can leave marks, so test it gently.

4. MIDORI Pen Holder Band — Best for Travel
The maker’s accessory listing describes an adjustable holder band designed around B6-to-A5 notebook sizes and two ways to secure a writing tool: by its barrel or by its clip. That can keep a planner shut and its pen attached for commutes or school. Check your notebook’s actual width and thickness; labels such as A5 do not describe every cover’s thickness.
Buy if: a planner moves with you from desk to bag and you want to keep everything together. Skip if: your notebook always stays at home or the band would press heavily on a delicate binding.

5. Built-In Pen Loop — Best No-Accessory Value
Before ordering anything, check the notebook or planner you own. Some covers already include a sewn loop or a slot for a pen clip. If that arrangement retains your pen reliably without bending pages, a second holder adds clutter and cost, not value. Replace a worn cover or add a holder only when you have a real fit or convenience problem.
How to Find the Right Fit
- Measure the thickest portion of the pen that will sit in the loop, not just the tip.
- Check whether the loop holds the entire barrel or only the pen’s pocket clip.
- Examine the back and inside cover for a flat, clean adhesive surface.
- Position the pen where its cap won’t protrude uncomfortably past the notebook edge.
- Test the setup with the notebook inside your usual bag before trusting it on a trip.
Should You Attach the Holder Inside or Outside?
A common adhesive position is the inside back cover with the elastic projecting past the page edge. Inside placement hides the base but can create a bump beneath writing sheets if installed too close to the spine. Outside placement leaves the adhesive exposed to more wear and may snag bags. Follow the manufacturer’s installation guidance for your specific accessory, and avoid obstructing hinges, straps or closures.
Is a Premium Holder Worth It?
If a cheap holder keeps shedding adhesive or stretching out, a well-made reusable clip or compatible branded loop may justify its price. But a good pen loop is a small convenience item, not a performance upgrade to your writing. Pay for reliable attachment and the correct size; skip decorative bundles that add no practical improvement. When comparing multipacks, divide the total cost by the number of holders you will use.
Common Mistakes
- Buying a standard loop for a fat fountain pen without measuring it.
- Assuming adhesive can be removed from a paper cover without damage.
- Clipping metal onto a valuable or fragile notebook cover.
- Ignoring pen length, weight and the possibility of sliding out.
- Buying a band without checking planner dimensions and cover thickness.
- Adding another accessory when the existing cover already holds a pen.
FAQs
Will an adhesive pen loop ruin a notebook?
It can leave residue, tear paper fibres or lift a surface finish when removed. Avoid permanent adhesive on valuable covers or choose a removable holder.
Can I use a loop with a fountain pen?
Often, but check size, grip shape and cap security. Carrying a costly pen hanging outside a bag creates risks even when it fits.
What about pencil clips?
Some holders work with pencils, but a slim pencil may sit too loosely in a wide loop. A built-in clip or narrower elastic often makes more sense.
Do pen loops fit softcover journals?
Some do, but thin flexible covers may buckle around adhesive bases or clips. A separate notebook pouch can be safer.
