I don't have the TNG Pez set but I do own the TOS version. I wish they had done one set for each of the five live-action series, but with Voyager
they'd have had to omit a couple of characters and/or skip making a dispenser of the ship because, as we know, at any given moment there were nine main cast members. The Pez gift sets held just eight dispensers.
Still, it would have been fun to get all the series.
