using really old, dry prints

I have several spore prints that I've collected & received from friends - some are probably 2-3 years old, all are on foil, and each individual print is in a little tiny ziplock bag still inside the letter envelope in which I received it (they were all mailed to me). I keep all these envelopes with the spore prints in a drawer in my kitchen.
Just so I don't delve into a fruitless endeavor, is there a point at which the spore prints are no longer viable? Are there any special measures I should take with a really old & dry spore print versus just taking an inoc loop and swiping it over the petri? (like does it need to be re-hydrated in some way, and if so how?) thanks

you mean squirt some sterilized water onto the print and let it sit out on a table out of the little ziplock bag & soak up the water over the next 24 hours? how many cc's of water? I'm guessing really a few drops is all it needs, no sense to totally soak the print or anything ??

He was talking about making a spore syringe.

And spore prints can last for many years if stored properly. Ive heard well over ten years.

oh sorry about that - nah, i don't want to make a spore syringe, i just want to take my old prints and put them onto agar. i was just concerned that they are so old and so dry (a few of them I know for a fact are about 2-3 yrs old) that they would need to be re-hydrated in some way before swiping them into a petri dish. if they'll work as-is just like a fresh print would, then that's good news

You dont need to rehydrate them. Straight to agar will do
