OptiPak Anti Fog Spray for Glasses - Eyeglass Lens Cleaner Spray 30ml/1oz 4pk

The anti-fog was surprisingly effective, particularly on my smartphone screen. On lenses, it works too, but not as well. For lenses, you need to be careful not to create marks or streaks on the glass. The included application cleaning cloth is nice quality and appreciated. There seems to have been some degree of leaking during transportation, as there was a wet portion of the box upon arrival, but I wasn't able to find any evidence of leaking from either of the sealed bottles themselves, and the wet stain disappeared the next day, so it's not a big concern.

To be honest there are other products that are much cheaper but I must say that the quality and the product itself is very impressive. I think I will continue getting these.
