Use for Dell/Silver Comics.

These are good when they work, but often they will split at the top when inserting the comic, or even simply opening up the gag a smidge to begin to insert the comic. On my last order, all but one bag was completely pre-split down the side. They made good on a new order, but it's getting frustrating. Otherwise, comics look great in these bags.

It's hard to beat how good a book looks in this bag. Add to that the stiffness it adds, you really can fall in love with a book all over again. That all being said, you must put up with a few quirks. As mentioned, the edges tear very easily if you don't put a board or book in straight. I've started keeping a little packing tape snippets handy to fix rips so I don't waste bags. The tape is clear and small so I don't notice it, but it's annoying. Also, since you must pre-crease the flap before storing a book, it can be tricky getting it in there with a sturdy bent flap pressing against the book threatening to bend the spine. Finally, if you decide to use the .40 super-acid free boards, you will need to bounce the bag against a soft surface (carpeted floor) to get the book to he bottom. Doing so can cause the bottom seam to rupture if you don't hit it square. I also feel that the snugness might cause the cover to tilt slightly away from the pages on the bottom right corner, but with silver age books, this is always an issue. All in all, a great bag if you do it right. (about 3 out of 5 tries are perfect). My advice, practice with a few throw-away books first!
