Do these expire? Will they dry out after some years?

I don't know. I use them up fairly quickly. I have had them up to a year and they didn't dry out.

They are sealed in foil wrap so they should be fairly air tight . . . I'm been using the same box for several months with no problems at all ... not sure what you mean by "years" . . .

To date have not opened a packet that has not been moist. There is a lot number on each packet but no expiration date. The lense cleaning wipes do not streak.

I believe they do have an expiration date but it would probably be dated out a year or two.Jessica CulbertsonPet Solutions

Yes, there is an expiration date. Typically they are good for a year or so. Mine did not expire until 2016.

They usually have at least a year till they expire. I buy them all the time. Best price you can find

I do not see an expiration date. These are heavy dark glass pharmaceutical grade jars, and if stored in a cool dry place should last many years. They are usually long gone before any worry about expiration.

I don't see an expiration date but they do seem harder and drier than I expected after they've been on the shelf for several weeks. My dog was scarfing down one a day but she is less eager now that they seem dried out.

No I don't see an expiration date. But if they are sealed and in a cool place they should last a long time.

They are freeze dried so should last indefinitely if sealed. If left open, moisture could get in and cause spoilage.

It will depend on when you order. The last ones I ordered were good for about 9 months. I have never gotten any that expired before I used them up. I test myself monthly.

I have had them up to 8 months without any problems. I keep mine in a cool dry place.

Not sure about expiration dates, but they work fine and last long - even if left in a drawer for weeks at a time. Great buy, especially if you think how expensive they can be over the counter in a retail store.

Yes they do, the ones I got last month expire on 11/01/2015. So they have a decent shelf life if left unopened. I refridgerate after opening.

Bhavik, The do not have an expiration date on them. However I am sure if you leave the package open to the air, they will absorb the moisture in the air and they will lose their drying. I actually reseal the package after I have used the ones I need in a vacuum seal pack. Mine have lasted for months. Hope that helps. Steve

There is no expiration date but a best by date which is about a year out from when they are produced. I would think the bars will last long after that date if kept in a dry cool space.
