IMO the holders look crappy and are terribly inconvenient to store. As you point out, though, the items are very fragile, and some sort of holder would seem to be proper. I wish there was a holder similar to a card saver in terms of thickness but sealed and labeled like a slab. CGC [the comic book people] had one going for a while for photos but it was a test that never really got traction. Too bad. I have several of them [see below] and really like how they store the photos without being ridiculously thick and heavy. Not every item requires a pound of polystyrene.
