How long does the ink in each pen last? (pen lifespan)
93058
Depends on how much you use it. I've been using these pens for decades and am quite satisfied with their lifespan. The only thing is you must put the cap back on after using the pen or the point will dry out. That will shorten the lifespan of the non-retractable type pilot pens. The retractable type don't have this issue. I use both.

I don't know precisely how much ink these cartridges contain, but, they were shipped in new condition within manufacturer's suggested freshness dates and I am a graduate nursing student/writer. The cartridges will last on average for 2 months (for me). However, since I will print several hundred pages within that time frame, I would consider myself to be a high-volume user. I usually replace the cartridges twice a semester.

The ink dries fairly quick. To be safe, I usually wait a minute, just to make sure its completely dry. It all depends on what you're using them on though. Hope this helps!!

I do quite a bit of large print printing; I would say that they lasted me close to a year. I use my printer for only personal, not professional printing.

I cannot give you an answer as I'm out of the country but I'm certain that there is an expiration date; however, I expect the ink will be good for two to three years past the purchase date provided it is stored properly. This is usually the case since the ink containers are sealed units.

Ours have lasted more than a couple of months, but don't know exactly. We print daily 10 pps.

I don't remember the exact number of pages or amount of time the starters lasted, but it wasn't long. They last longer than ink jet cartridges. I haven't changed the colors, but we primarily use black. This replacement set has a longer life span. Do not replace cartridges when the printer tells you to. You can take the cartridge out and vibrate it or shake it flat to loosen up toner and lengthen the life. Also, HP tells you WAY to early to change it. Just keep the cartridge in until your copies start fading.

I don't use the printer everyday but the tanks are pretty full of ink so I am assuming they should last for a while. They look pretty cheap quality but you cannot beat the price. Best buy sells one tank for 20 bucks.

No, when these pens are done, they're done and you have to buy a whole new pen. They last quite a while, though, so I've yet to need to purchase anything new, and I bought them quite a while ago!

They seem to last a long time. I use mine in the shower, so I usually clean iTunes running water, then just put it in the cradle for the dry cycle. Occasionally I run it through the cleaning cycle, and the cartridges are lasting about 4-5 months each.

The Ink doesn't expire. It does have a "limited warranty date" which may or may not still be valid.

I've had my box for a few months, I have no idea how long they last, but they work great in my Epson 520 printer, I just keep my unused ones in a cool dry place, for that many at that price, great!

I honestly don't have a precise length of time to answer this question. However, I can tell you with ALL certainty that the things I have drawn/written with this ink have lasted at the very least a YEAR and I don't have any doubt that it would last even longer because it's a permanent/bullet proof ink. I guarantee that you will not be disappointed. I have used Noodlers inks in the past and I truly enjoy their unique hues. This ink is a wonderful novelty and I am certain that if you are on the fence about buying it, you will not regret it! Tons of fun!!! AND it truly dries INVISIBLE. ***Word of caution, make SURE that ALL traces of the ink you may have used previously in the pen that this "Ghost" in will be going in is COMPLETELY cleaned OUT of the pen, or you WILL see this ink. At first, I thought that this ink had a very light blue hue to it and I could actually see it on the paper (I was getting discouraged that it wasn't actually invisible after all), but then I remembered I had previously used a blue in this pen. I really thought I had done a great job of cleaning it out, but when I disassembled the pen, I found a cranny of the piston housing had a small glob of the blue ink. Once I cleaned it out thoroughly, I did NOT see the ghost ink when I used it; it is TRULY invisible!!! Very impressive. AND bulletproof, meaning that it won't run under water and is tamper proof. I hope you enjoy the ink as I have! Cheers!

The package for these units are well sealed. They are marked that they should be used within 6 months after the package is opened.There is no indication that this life span in in anyway connected with the Computer chip. i suspect that the warning may have more to dowith the action of air on the ink. I have had no problem with age of these units and I have exceeded the 6 month time on my installed itemsSo far I have had no problem with the Brother inks not working because of age.

I use my pen daily and the tips have lasted 6-7 months. I purchased the replacement caps without reading that the cap end was not replaceable. If you use both ends they both wear out, duh. Why would you only want to replacement ONE end. I like the pen but wouldn't buy another until they make BOTH caps replaceable.

Usually, there is an expiration date on the box, e.g. I just bought a package of 4 ink cartridges (1 black XL, 1 each Cyan, Magenta, and Yellow) to hold for when I need them, and on the box is an expiration date of "Nov. 2015." That gives me approximately 19 months. But you can be sure I'll use them well before that date.

Hello, first of all my pens were garbage, none would write. I just threw them out. As far as I could tell the pen nibs were all the same. Hope you have better luck.
