Check on Kickstarter

Last year, we received an email from one of our customers in Ohio suggesting the development of the EDCEST PEN. After months of development, we sent the prototype to him, and he loved it, as did we. Carrying a pen can be cumbersome, as the shortest pen is still centimeters long, and you need a bag or a pocket. That’s why we created the EDCEST PEN.

The pen

Tiny yet comfortable, thanks to its thin, wide, and flat design

Thumbnail-sized. Smaller than a bottle cap.

It would be considered just a toy if it were only tiny and uncomfortable to use. Our pen is made to real use. The pen measures 23mm x 17mm x 4.5mm(we might make it thicker:5mm) and weighs only 1g, including the refill. Despite its small size, the pen’s unique flat and wide form makes it surprisingly comfortable and stable for drawing and writing. Both pens and sheaths are 3D printed with PA12 using industrial-grade SLS 3D printers. PA12 is a long time-proven, robust, skin-safe, and waterproof 3D printing material. To achieve consistent 3D printing quality, we underwent numerous tests and have been adjusted to the optimal dimensions. 3D printed with PA12 from Sculpteo in France using industrial-grade SLS 3D printers.

Please note: Avoid using the pen tip to cut box tapes on packages for opening.

The Sheath

Two color options – Black(dyed in black), Grey(solid grey)

Black (printed with white PA12, SLS, dyed to achieve black color)

It’s not just about how small the pen is; it’s about how you carry it. You can ‘wear’ our pen on your wristwatch strap, even when you are naked. There will be 14 sizes. Just like the pen, they are 3D printed in one piece. Here is the list of The sizing options include 18mm, 20mm, 22mm, 24mm, 26mm, Apple Sport Band 45mm (21.7mm/2.7mm), Apple Sport Loop 45mm (24.3mm/3mm), Apple Milanese 45mm (22.6mm/2mm), Apple Leather Loop 45mm (23.3mm/3.5mm), Apple Alpine Loop (26.5mm/2.5mm), Apple Trail Loop (25.7mm/2mm), Apple Ocean Band (23.5mm/4mm), and Gshock 5600/5700/GA2100 (two sizes for this strap: for a wider area, it is 23.5mm/2.7mm, if you want to wear it on a narrower area – recommended – it is 19.5mm/2.7mm).

Please note: For maximum compatibility, choose the general sizes(20mm, 22mm, 24mm, and 26mm). They fit up to 4mm thick straps.

How to install

Select the sheath that matches your preferred watch strap and slide it onto the strap.

How to use

To deploy the pen, lift it with your index finger while pressing the thumb studs for support. With tactile feedback, the pen will smoothly come out.

How to change a refill

The remaining ink is always visible through the ink windows on each side. When you need to change the refill, use the rear hole to push the refill inside, using the rear end of the new refill (do not use the pen tip to push).

Wide compatibility – Use your favorite refills

Pens will be shipped with extra refills, and you will be able to purchase pre-cut refills from our store(black, 0.7mm). Refills will be proudly manufactured in Korea. Since there are many pen manufacturers producing excellent ballpoint pens, and individual preferences vary, we have identified that the most common refills come with ink tubes of 2.8mm~3.2mm diameter. This size represents the global standard for retractable ballpoint pen refills. The EDCEST PEN was designed to accommodate these standard sizes, allowing you to purchase refills from your local store. In our tests, refills for multi-color retractable ballpoint pens from BIC, Zebra, Uni Jetstream, Monami, and Dong-a fit nicely. All you need to do is cut the refill about 27mm from the tip to the rear end.
