My objective lenses are wonderfully clean the optics paper, no more streaks, they provide perfect cleanliness. Prefer not to miss them, as the cleaning process each time was an effort, and the lenses were still not completely clean, I think the towels of course very good. Delivery was on time on the day. The packaging was good, the price of the lens cleaning cloths, 150 pieces, simply unbeatable !! I'm very satisfied !!
