How long does it last before it is no longer usable (e.g., gets old / expires)?

It really depends on how much you use it, but you can get a "reinker". You add some of the reinking fluid to the sponge and it will be good as new if the sponge is still in good shape. Just search for Perfect Medium reinker. You can find it here on Amazon. Hope this helps!

its on the package somewhere (i believe the bottom of the outside) and it says a expiration date which is usually at least a year if unopened.

The expiration date on the box I have left is for the Year 2017. I use it daily, so it doesn't last long.

Hi,That is what I've been doing and I've had no issue. It might eventually expire, but so far I've had no problem! This stuff was a life saver...literally! Lol

It's usually about a year. They all have expiration dates. So if you purchase in larger quantities you need to plan on out your usage to avoid having them expire.

I've never noticed an expiration date on it. I can tell you that with the small amount that I use each time, mine lasts well over a year and still works great.

I've used some that were very old. Always worked fine. I don't think expire. Why is that important?

I'm not sure if there's an expiration date, but it still works after fairly regular use.

It depends on how you are using it. I use it primarily in recipes so mine will last a couple of years. If you are using it straight out of the container, you need very little, so it still will last a long time.

My current purchase expires December 2015. You'll have about a year until expiration.

I don't see expiration date, but I do see the packaging has copyright ©2012. I can tell you when it runs out if you want.

It should be fine up until that date, or in my experience some time afterwards. The only way these things go bad is if the packaging is damaged or punctured in some way, or if you leave it for years (months is probably OK).

I've had mine for about 10 years. I use it for 20-30 minutes almost every morning, six months of the year. I guess I still haven't hit the expiry point!
