Very cool combination
These look great on my white New 3DS. Incredibly vibrant! These are great if you want to make a visual statement with your portable gaming.
Keep in mind that they're translucent and you will see the 3DS's actual shell and battery through them. I don't have a black one to compare, but they catch a lot of light and would probably still show alright. I held them up to a black speaker and they're still fairly visible that way.
It's good to have a can of dust off when you put them on because dust will get inside and you'll have to look at it.
I baby mine, but it looks like the plastic would scratch easily if provoked.
