You guys know what I'm talking about, right? The little white or black plastic wands that came in the official NES cleaning kits? They've got some kind of I guess fabric on either side, one side you wet down and use to clean the cart contacts, the other side you use to dry them.
Anyway, these things are great. They always seem to do the trick for me, often times without even having to wet them down.
I know Nintendo used to sell them for pretty cheap on their website, but I can't seem to find them there any more. Does anyone know where I can get them now? I'd like to see if I can get them in bulk, if possible.
