Designed for precision, it creates durable 1mm conductive traces on a wide range of surfaces including plastics, metals, ceramics, and 3D printing materials. Its valve tip and soft tube allow controlled ink flow, making it ideal for professional prototyping, electronic repairs, and hobbyist projects seeking reliable conductivity without the premium cost of silver or nickel paints. ## Description The 838AR-P carbon conductive pen is a conductive, fast drying paint in a convenient pen format. It quickly and easily creates conductive traces that are durable, reliable, and corrosion resistant. It adheres to a wide variety of substrates. The paint is a tough acrylic polymer pigmented with high purity Carbon black. The Carbon black imparts superior corrosion resistance as well as high conductivity. This product works best on smooth, flat, and hard surfaces. It has a Valve tip that opens when the pen is pressed against the surface to be drawn on and it has a soft tube, so the flow may be controlled by squeezing the center of the pen. It is used to draw resistors and connect grounds in prototyping, hobbies, or Maker projects. It can be used to create traces where a higher resistance connection is desired such as when drawing in jumpers or other simple electrical connections. It is good for restoring conductivity to contact surfaces and extending contact areas. Use it as an economical alternative to nickel or silver paints where extreme conductivity is not required. Attention! shake rigorously before use. For best results hold pen at angle, depress pen tip against surface, and draw pen across surface while gently squeezing middle. Review: Worked Perfectly for My Needs - Repaired Carbon Traces in Game System - I was working on a Turbo Express system with non-functional buttons. The capacitor on the controller board had leaked and dissolved the carbon traces for the buttons, so I purchased this carbon ink to see if I could use it for a more 'authentic' repair rather than jumping the traces or replacing the board in its entirety. After practicing drawing a bit on some regular paper, I cleaned the traces thoroughly, took a bit extra off the damaged sections and contact points and carefully applied the carbon ink. Most went on pretty easily (follow the instructions, they are helpful) however there were a couple spots where I flowed a bit too much and had to clean / reapply. Overall, it took maybe 15~20 minutes to read the instructions, practice a bit and perform the repair / get it how I wanted it (this being my first time using conductive ink, so next time it shouldn't take as long). My repair is barely noticeable! Most importantly... I let it dry for 10 minutes and tested everything out, and all buttons worked perfectly! This stuff is a God send. Follow the instructions and it really isn't difficult to properly apply... Make sure you thoroughly clean any surfaces you plan to write on, and remove a bit extra from damaged sections and contact points of existing traces, squeeze the pen firmly but not excessively while applying pressure to the ball point and use deliberate motion... Great product! Review: Keypad repaired - Used this to repair the contacts on a garage door keypad. Works like new.

First, clean the circuit board where the contacts are using Isopropyl alcohol. I also used Iso to clean off the rubber dot, which is usually a conductive carbon substance. Then apply the *carbon* version of this product to the black dot. Cover the whole surface and let it dry completely before re-assembling. **Q: Can this be used to repair a broken strip in a car rear defogger?** A: I just tested a 1/2" long x1/8" wide strip on a piece of pyrex glass and got 0 resistance for that length. It seems to conduct well for a short distance and stuck to the glass very well. I hope this helps. **Q: Does it work for making a PCB?** A: In my opinion, it's far from the ideal for making your own PCB. I can see it being used for prototyping of low voltage/low current circuits.This particular compound is based on nickel, which is not a as conductive as copper.This pen would work fine for the small repairs like cuts or tears in the existing PCB traces. BTW, there's a more conductive version of this pen which is based on silver.Aside from conductivity issue, there's an issue of securing parts to PCB. I,also, doubt you can solder to the trace drawn with this pen. **Q: Is this pen good for making a jumper on a circuit board?** A: Yes, it's great for that but even the carbon conductive (lowest quality) pen would work for that ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked Perfectly for My Needs - Repaired Carbon Traces in Game System *by P***9 on 18 July 2022* I was working on a Turbo Express system with non-functional buttons.

Great product! ### ⭐⭐⭐⭐⭐ Keypad repaired *by W***N on 4 September 2024* Used this to repair the contacts on a garage door keypad. Works like new. Recommend ### ⭐⭐ Naaaaja... *by S***K on 31 August 2024* Kann das produkt nicht guten herzens weiterempfehlen. Ist zwar conductive, aber das ist ein gaphit bleistift auch. Auf 1cm strichlänge hat man schon 120k ohm widerstand, bissl weiter gehts in den mega ohm bereich. Der widerstand is so gross, das man nichtmal bei 2mm linie einen ton aus dem multimeter bekommt wenn man auf durchgang testet..kann nur widerstand messen. Mag vielleicht bei nem kratzer auf ner pcb leiterbahn helfen um zu überbrücken..mehr aber auch nicht. Bei dem preis gibt es bessere möglichkeiten ein pcb zu fixen. ## Frequently Bought Together - MG Chemicals 838AR-P Total Ground Carbon Conductive Pen, 4g - CaiKot 44, Conductive Silver/Carbon Coating for most surfaces --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/223942954-838ar-p-total-ground-carbon-conductive-pen-4g](https://www.desertcart.gr/products/223942954-838ar-p-total-ground-carbon-conductive-pen-4g) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-15*
