How long does the ink in each pen last? (pen lifespan)

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.

These lasted about 6 months. We only used the smaller versions when we first bought the printer and I can't remember how long they lasted - but it wasn't very long at all. Sorry I can't give a direct comparison. I would say our printer use is moderate to high.

It, really; depends on how much and how often you print. Mine last quite a long time , but I don't print that often.

This HP ink does not expire. Look up this information directly from the HP website. The date you guys are seeing that is stamped is the warranty date. Anything after that date HP will not replace (assuming you bought direct).

The Lamy cartridge lasts a little less than one month in my hand with constant use. My pack of 5-refill came on 5/22/13 and I am now using the 3rd cartridge. Hope this helps.

Hey Caitie. I rarely use the pen so the ink hasn't dried up yet. I am sorry. Good luck and let me know if you find any replacements.

The point on this pen is not particularly fine, and is comparable to most ballpoints. It takes the PR-series cartridges, which are available in finer points: http://www.spacepen.com/cartridge.aspx I can't tell you how long they will last, as I've never had one run out before losing it. They will last for at least four months of heavy, daily use, as that's the longest I had one.

I believe the nib will last a long time if the pen is taken care of and not abused. I've had my pen for over a year and have had no problems.

For the most part yes, they don't last as long as a normal pen. But they're not too bad given the price.

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 do with 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 items So far I have had no problem with the Brother inks not working because of age.

Hi Jerry. Each individual pen has Germany lightly engraved towards the bottom. Each pen also has an Art. No. 88/94, No. 88/96 etc. I use two shades often and the ink content has lasted some time. However I only use them to write and not necessarily for drawing so I'm not sure how quick the ink runs out for the latter use. Hope this helps.

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!

My opinion....since they are laser cartridges and use a powder, not liquid ink.....as long as they stay dry, low humidity....they should have very long shelf life.....6-8 years.

I use them at work where I write notes and my signature 4-5 days a week. They last me about 3 months before the tip stops working on all sides. Then I have a few more weeks of writing if I find the "right side" but usually I get sick of it and just grab a new one. I love them though! I used to buy Sharpie pens until a friend slowly convinced me these were better.

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 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.
