Let it be your pocket, keychain, or anywhere else; the EDC keychain pen from True Utility can be kept anywhere for your daily usage, especially when you need to write some quick notes.

Thanks to its compact design, it seems to be as tiny as a regular door key!

This telescoping keychain pain is just around 2 inches (when closed), and when it’s extended, the pen won’t be more than 4 inches. Thus, it makes a perfect match with any tiny keychain.

Talking about the build quality, it gets 420-grade stainless steel to maximize durability and longevity.

Titanium Keychain Pen from TISUR


  • Pen Size: 3 inches
  • Material: Gr5 Titanium

As the name suggests, the keychain pen from TISUR has included top-notch Gr5 titanium, making it sturdier and even better than the traditional ones out there.

Not only it’s a keychain pen, but this one right here is necklace-friendly as well. Even it might be combined with a carabiner or can be kept smoothly in your tiny pockets. And it weighs only 0.81 ounces for portability.

I personally liked its ergonomic design, along with the anti-slip grip. These all play an essential role in offering a great hand feeling.

On top of that, your writing will be smooth and precise, especially if you use LAMY refills.

  • Weight: 1.1 Ounces

Measuring only 3.3 inches, ARROW and EAVES 43835 seems so small in size to make a perfect match with your keychain and tiny pockets.

When you extend the pen completely, it appears 4.9 inches with a size of 0.31-inch standard grip for smooth and comfortable writing.

The titanium keychain pen has got your back if durability is what you’re concerned about; aircraft-grade alloy steel with a combination of five-grade titanium makes this mini titanium pen one of the sturdiest ones I’ve ever seen so far!

5. Stylus Keychain from Sidelinx

Stylus Keychain from Sidelinx


  • Pen Color: Silver and Black
  • Quantity: 2 Pack
  • Weight: 0.317 Ounces

On number 5, I’ve got a 2-in-1 keychain pen from Slidelinx that is well-equipped with a built-in touchscreen stylus you’ll find on the outside.

So it keeps your hands away from touching unnecessary stuff, for which you can protect yourself from harmful germs and other such things.

Also, it’s suitable for your personal tablet and smartphone!

Here, you’re getting two packs (silver and black) instead of one to use the mini pen keychain for an extended period. I’ve found it super smooth and ideal for quick signing.

By just attaching the pen with your necessary keys, it’s possible to always keep it with you. You can also keep it inside your purse or pocket in case you don’t have any keychain. Trust me; it isn’t going to eat up a lot of space at all!


  • 2-in-1 mini keychain pen
  • Suits small pockets and keychain
  • Smooth and non-slip grip
  • Suitable for smartphones and tablets


  • The tip seemed way softer!


The Stylus Keychain from Sidelinx comes in a 2-in-1 feature, making it suitable for writing and operating smartphones and tablets through its touchscreen stylus.

What to Look for Before Buying

Since the current market has got over hundreds of different keychain pen models with different pros and cons, it might be challenging for you to get the best one, especially if you don’t have the proper knowledge about this pen.

So make sure you keep the below-mentioned things in your mind before making an ultimate purchase.


Before getting a keychain pen, don’t forget to consider the material first. Aluminum alloy, stainless steel, titanium; are some of the popular and durable materials you should choose for your keychain pen.

Point Type

The point or tip is one of the main factors of a keyring pen as it helps you write smoothly, replace the cartridges and refill the ink with ease. So, you must pay attention to whether the tip is working well or not.

Try twisting or unscrewing the tip when you are at the shop. If you’re unable to unscrew it comfortably or get stuck while twisting, avoid buying those pens.

Ink Color

It doesn’t matter whether you’re a doctor, nurse, student, or teacher; I always suggest buying the “black” ink instead of any other colors. It’s more formal and suits everyone best.

You can also go with the “blue” one if you need a keychain pen just for informal writing purposes.

Size / Dimensions

There is no doubt that a lightweight and compact keychain pen is handy or more convenient to use. So make sure you get your hands on a mini pen keychain, which should be easily attachable to your keychain or can be kept inside your pockets.


Indeed, some refills are universal in many keychain pens, and some are not.

Universal ones are super easy to handle, even if the ink runs out. Conversely, other top keychain pens may feature some customized or unique shapes.

Trust me; there is no need to get the most expensive keychain pen if you want to get a model with refills. Yep, it’s possible to find a comparatively cheap keychain pen that offers free refills!

Final Verdict!

The purpose of writing this review was only to give you the best keychain pen for your daily usage, especially if you have to take some quick notes every once in a while!

But if you still can’t make a final decision about your purpose, I’d suggest you spend your cash on the Keysmart ‎KS810SS. From excellent ink quality to durability, this one is by far the best tiny pen for everyone, in my opinion.
