The Hard Case stores your PSP and two UMDs securely and features a secure closure. I am unable to determine whether stored games come in contact with the PSP screen or not, but it would be a close fit, so I advise using plastic screen protectors in conjunction with the Hard Case.
The Hard Case is a good solution for the gamer who has a bag they carry around already that they could keep it in or anyone who always seems to be rough on electronics. It also might be a good solution for gamers in areas that tend to have a lot of unexpected rain - fabric cases aren't very weather resistant.
