This marker was never opened until 11 months after purchase and it does not write. It was not left outside but in the kitchen in a drawer.

It takes a wh8le to get the paint down to to tip....shake like crazy and push down to fill tip and try that. If you had used it before it may need done again. Otherwise maybe it dried out.

Unopened , it is good for 10-12 months. Once opened, it is good for 4-6 months. Please store in a cool, dry place :)

The expiration date is smudged; it could be October of 2013 or October of 2018 - I cannot read it. If it expires in 2013 I will probably have plenty left and will just continue to use it until it is finished.

The brand I bought had an expiration date. That date was several years. Mine have lasted at least a year if unopened.

not sure but one possibility is that the ink will no longer be good if it isn't used by the date printed on the package. I have always used up the ink well befoer the date on the package so have never had that problem. I would certainly not buy a package that has an expiration date that is not at least six or more months out from the date of purchase.

Not well. I think it's a water-based ink. It is kind of splotchy on most plastic - and ....I just tried wetting my finger after it dried for 5 minutes and could easily wipe the ink off the plastic. Then I tried a red and a blue "Sharpie" brand permanent marker - the most common type of permanent felt tip marker pen - and couldn't remove the mark after it dried for a minute. However, the calligraphic pen is permanent on paper - and the pens stay good for years - sometimes even surviving when they are left uncapped for a while. And their chisel points keep a nice shape too. Makes average handwriting - like mine - look fantastic. enjoy, Roger L. Not well. I think it's a water-based ink.

One year. I keep mine refrigerated at all times. No exp date on bottle, so I write my own exp date in marker upon receiving.

Mine had a 'best if used by' date on it. It was about 11 months out from the date when purchased. It seemed fine for many more months after that though.

Mine is in a tube, there is no expiration date on the tube that I am able to decipher . There are numbers and letters, "not" resembling a date.

it doesn't have an expiration date. label says to store in a cool place, undiluted.

I don't see anything on the tube and I have already discarded the box, so I don't know if there was anything printed on it regarding the expiration date. Btw, I have seen the same "EX" typing on my tube as the others, but I am not sure what that means.

Just on the wrapper. If I remember correctly there is no writing on it at all after u open it up

The manufacture does not specify any expiration date. Thus, a consumer may use it for several years ( if need be) after opening.Feel free to email for more information or purchase. Hasaunk@gmail.com

I don't know for sure, I just know once opened, its only usable for a month. I think there might be a date on the bottom of the container if it isn't opened.

Instructions on the actual brik label state to write the date you first use it(after removing label to activate), then discard it two months later. Haveing just purchased this recently, I am on my second brik.

"already expired", but.....I have the HP1100d running on Windows 8 and am using the HP1000 driver without the fancy HP programs like ink level and so on. that being said, the expiration date means nothing to me.
