RE:Classic UMD cases
I had been using the Hori made slide in cases which are great except they can leave slight slide markings on the UMDs so I thought I would try these open/close ones...

They are good if you are careful when you put the UMDs in and out as they snap into place underneath a small piece of plastic on either side of the UMD. If you are not carful putting the UMD in or getting it out you may damage the UMD.

Not really ideal for young kids then...but then again how many PSP users are young kids?

At least they wont fall out of the case which might occur after using the slide cases for a while (if they wear down?).

Overall a good buy.

The Perfect Cases!!!
After looking for a good cases finally I found these and I have to tell you that they are better than what I could think.
They totally protect the UMDs and fit them perfectly without any scratch. The colours are beautiful and you can see clearly which game is inside the case. Now I can bring with me any game without a big box (I recommend the Aero Case because you can put two games with these cases in it without any problem).
If you want cases for your UMDs don't think more, buy these, they are the best!!!
