What a rip off, I was expecting them to have some sort of solution in them to actually clean the disk. This is just an overpriced piece of paper. I should’ve just used a new microfibre cloth and some rubbing alcohol. Yes they removed finger prints as advertised but if there’s anything else like gunk or paper stuck to the disk from DVD packaging this is not going to take it off. Easy to use yes, you just wipe, value for money a total rip, thickness is the same as toilet paper in an airport almost see through
