It is very old. I don't remember when I purchased it. Even though the shrink-wrap is still intact, I see some black stuff? Is that mold? This is run of the mill Honda A02 filter but still it would not want to throw it away unless really necessary.
I think you're seeing glue. Since it's been shrink wrapped it should be just fine IMO. Moisture/humidity can compromise filter media over time but with the shrink wrap I doubt that's a problem. I'd run it.
I would take off the shrink wrap, since you are either going to use it or throw it away, and feel if it's glue or something else. Glue, no problem; something else, problem.
Agree that the black stuff is in all likelyhood glue, tapping plate to canister body, a common glue area for filters. Remove shrink wrap, as long as no surface rust visible, use with confidence. Shrink wrap increases chances filter is good to go.

+1 ... My vote is you're seeing old oil/grease left over. Put some WD-40 on a rag, and see if it wipes off clean. Filter should be OK if there is no signs of rust anywhere.
The Honda A02 is a good filter, but that black stuff does NOT look normal. I just went and looked at both of the A02's I have and neither had black around the edges. If I were you I would pass. Just use a different filter or buy a new one. They are cheap. I would not want to pump black gunk into my engine.

If its on the outside, it could easily be on the inside as well. Cant brush that off.
