3 1/2 stars Look at the Amazon page for the 8 boxes of 60 sheets of these for a more detailed product description.
I used this duster on a Swiffer sweeper. They are tacky; but, they don't leave a residue. I would not use these to clean tv, computer screens, etc. They are rough to the touch. These are primarily for industrial & office settings. The box graphic which shows the sheet as solid black when it needs to be changed is a bit misleading. My sheet stopped picking up stuff before it looked black. With that said, it does pick up stuff that a Swiffer misses; and, I was impressed at the difference between the dirty and clean parts of the sheet when I tossed it into the trashcan. I plan to use these along with my Swiffer.
