    How to change ink:
    Ink refill replacement is simple, but will vary depending upon the version of PicoPen you own. Please refer to the Refills tab for details

    The PicoPen uses a standard D1 "multi-pen" size refill. We carry a generic refill brand HERE on our website for your convenience. We also carry the Monteverde premium refill HERE which is included with our Ko-Axis Rail pens.

    Please review the following images to determine which model of PicoPen you own, and how to replace the ink refill. If you have any questions or problems, please email us at: support@tecaccessories.com

    The PicoPen is available in a choice of 2 pen barrel materials, either stainless steel or aluminum bronze. It should be noted that aluminum bronze is considered a “living finish”. Similar to brass and copper, when exposed to the elements it will have a tendency to oxidize over time. This oxidation, also called patina, can be either beautiful or unappealing depending upon your personal preference.

    If you prefer the look of patina, simply use your PicoPen as intended and over time the barrel will develop its own unique appearance. However if you do not prefer this type of finish, this can easily be corrected. There are many over the counter polishes or homemade solutions that can be used, but the most common is a polish called Brasso. Simply use a very small amount on a soft cloth and wipe down the aluminum bronze LIGHTLY around the barrel. You do not need to apply pressure, it doesn’t take much effort to clean the material. This will restore the finish to its original factory finish.

    Customer reviews are very important to us. Please read this independent review In Search of Excellence A consumer product review of keychain writing instruments by Al Medrano, where the PicoPen took first place. 

    "The PicoPen has a wonderfully sleek design. It has the smallest footprint (size and volume) among those studied (except for the Swiss Army Victorinox). The inventive magnetic coupling concept makes this a "one hand" operation for detachment. Made of stainless steel, it is rugged enough to take a lot of punishment."

    Shipping Times

    PLEASE NOTE: Due to the current logistics delays, shipping times may take longer than expected. This is especially true for International shipments, where delivery times can take weeks longer than usual. This is beyond our control, and we ask that you please be patient with expected deliveries until shipping companies get back to a more "normal" schedule.

    We make every effort to process orders within one working day, however there may be slight delays depending upon the number of orders we receive, holiday periods and available staffing resources. Typically we will process all orders within no more than 2 working days.

    Shipping times (from the time the package is dropped off at the carrier) will vary depending upon the carrier, method of shipment and destination. For example USPS Domestic First Class Mail should take between 2-3 days, but we have seen instances of 5-7 days. Domestic Priority Mail should take 1-2 days, but can take anywhere from 1-4 days. Domestic Express Mail should take one day, but that is only if your processed order is delivered to the post office before the cutoff time (typically 12:00 noon). Also keep in mind that weather and travel distance can have an effect on delivery times.

    International shipments have even more variables that must be considered. A package sent by USPS First Class International can take anywhere from 1-3 weeks, sometimes longer depending upon the country. International shipments have the potential of being delayed by Customs, as well as having additional taxes or fees levied on a package. These are out of our control, and we advise that you become familiar with your specific country's shipping regulations to understand the impact to your shipment.

    Best pen

    Awesome pen put it in your keys and forgot it is there until you need it


    Perfect in a pinch. I have mine attached to a Dango S1 Stealth wallet and just makes for a fantastic lightweight EDC. Writes much more smoothly than I expected.


    Better quality than expected

    Still need for a pen

    I am a habitual notetaker, and I'm glad I found this pen. Always with me on my keychain, better than sporting that "nerd" look carrying a pen in my shirt pocket

    Everyone needs a good pen!

    In this digital world, a good unassuming easily carried pen can sometimes save the day. This is that pen!
