Not very good
I bought this case because I have a lot of Hori products and for the most part they've been great. Unfortunately this item was not, for a couple reasons.

The case is small which generally is good, but it's small to a point where the first or last flaps will get stuck when you open the binder. So you have to pry out those flaps most of the time.

There is also a little plastic part that is supposed to go over the top of the disc. Seemed like a good idea when I saw it, but when I actually tried to put a game in there it was a whole different story. It's practically useless, and makes getting a disc out much harder than it should be.

Finally the worst part about this binder, it scratches up your discs. I simply put the disc in for a second then took it out and there were scratches all over the outer part of the disc.

Overall not a very good product. It's cheap for a reason I guess.
