Although I'm aware this issue has been discussed in the past, I was wondering if anyone here knows of a good way to prevent the 3DS from scratching/smudging the top screen when closed. I love my original 3DS and don't want to upgrade to the 3DS XL or 2DS, so I'm curious what others here have done about it. Right now my current solution is putting an old credit card in between the two screens when closed which has done a good job so far. It is a bit annoying though, especially if I want to quickly close my 3DS for whatever reason.
