How long does each pen last?

I have had these for a year now and I use them every single day. I am not sure how it is possible, but they aren't showing any signs of running out of ink...

I ordered these pens about a month ago and they still are working. I am a college student so I take all my notes using these pens. I dont have an exact time but they are amazinggg

Mine have lasted a year so far. It is because it is only used a few seconds at a time with a pressure switch as opposed to a slide switch. It works really well for color pencil art. It allows for a very light touch.

I used them for about 10 hours total and the only one that ran out of ink quickly was the black one. 5 hours into their use the black one was half full. Also the tip wears down depending how hard you press so keep it light.

It depends on how heavy the usage is on your system. They usually last about 3 to 4 months with our system.

I would say they last a couple of years at least. The only issue over time is that the little balls on the end of each bristle eventually come off and then the bristles are very scratchy! Otherwise I LOVE these brushes!

Pen uses a single triple-A battery and maybe a rechareable or disposable version. Unless it is used many hours a day, the battery should last weeks to months, better than wireless mouse or keyboards! Lithuim batteries will give a long live at reasonable cost over all other battery types!

I got a box of 12 pens! It took several weeks but all arrived and I LOVE THESE PENS! They write on slick surfaces and have not clogged like other pens.

If they are not unsealed they will last probably forever but after they are in the printer I am sure they tend to dry out as any liquid does when exposed to the air. So far my ink has lasted an average length of time and I am in the dry air of Tucson, AZ. Probably depends on your location to determine the speed of drying time.

You can buy them as often as you want. I buy the 60 min cards which triples minutes and it lasts me about 3 months of mostly texting. You have a counter on the face of the phone that tells you how many minutes you have and how many days to use them in. I ALWAYS have way more days than minutes. As of right now, I have 113 minutes and over 300 days to use them in.

If I remember right it's probably between 4 and 5 inches long. It really is a small pen. Seems to be very well built and should last untill I loose it.

After 3-5 months of continuos use. I went 4 months with daily school notes and it's still got enough ink that it doesn't really have to be replaced, but it's still running low.

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.aspxI 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.

They typically last 6 months. It depends on how much you use it. I change mine every 9 months.

These are my girls favorite pens that they have had for several years & they haven't had any issues of pens drying out. Those are the only pens they want to use. Sorry you experienced that.

The insulin pens stay cool up to 12 hours. My husband also uses the cold blocks you can purchase at many drug stores. As the gel pack started to leak.

I'm not sure of a specific answer, but I do know that when I try to use the pens, they do take a bit of effort to make them write (some don't even seem to work). However, lately I haven't even been using the holder provided.

I cut the refills and keep going. The refills do last about 2 months depending on how much you clean the box. It really isn't worth it to buy the refills though because you can just use trash bags. They work just as well.
