Do you find there's a shelf life issue? Everything I've heard so far about
seals is that they have a maximum life of about five years - and more often
three or four. Something about the rubber breaking down internally.

I haven't found storage to be a problem as long as the seals are kept in
sealed plastic bags and out of the light.
