That it was an ad should be enough of a giveaway, that it was also on
the TV means it's incredible.

Desperate attempt to stay on topic: How long does presensitised board
last when the bag is sealed?  How about once it's been opened but then
sealed up?  (Not talking about what the manufacturer recommends, which
is probably going to be "after using your 2x2cm square, throw the rest
of the board away" but what folks have found for themselves...)

Cheers,
